    EMAIL PROBLEMS HELP!!!

    Locked

    by kherl ·

    Ok here is the story… I have had problems with our companies email address for over a week now. My ISP doesnt have a clue what is going on so i have began my search for answers on the web. We have not been able to recieve emails from certain addresses. The ISP claims that they are being delivered to us but they never get to us. We are using outlook express and have got emails from the addresses in the past with out a problem. This just sprang up out of nowhere. The computers are very basic, dont have any spyware, blocked senders list , virus protection, they are exactly how they were 2 weeks ago when we had no problems. My ISP is clueless on why the messages arent being downloaded from them. I have also tried to receive on 2 other machines with no success. Could anyone help?!?!?! What do i need to tell my ISP other than shove it and ill find someone else. THANKS FOR THE HELP!! please respond to kherl@swbell.net
    THANKS!!!!

      I ran into a similar issue (am still sorta daling with it) over the past wekks on two different client sites.

      They run their own mailservers so I have had the ISP’s run through a backup and that way they have record of all email passing through to the client.

      Some very important companies have just been sending email into cyberspace and they disappear.
      A revers Trace route shows it ending Bell South and a noted two unresolved hops past that. The sender is not having anything returned and it shows as transferred. Trace routes from their end show similar results.

      I have also had problems myself with overseas email coming in sporadically as well as mail from Eastern Canada.

      Telus (the local telco) has replaced routers and DNS servers due to undisclosed problems, even with DNS changes, this should still be OK now as they reset every 20 minitues.

      Mail seems to have been disappearing for quite a few people lately, I have had several service calls myself.

      MY business ISP has had his engineers in the US working on it and they are at a loss because all mail they receive is transferred okay, but mail simply isn’t seeing them for some reason.

      So with more than one company, more than one country, more than one ISp,more than one telco, I’d say something’s up that may surface soon.

      ???????

      OM

      Oh yes, this is a great place to discuss such issues, but the Technical Q&A section (link in left NAV bar )is the place to get such answers, although I’ve tried, though I solved it and some users are still missing some mail.

        Known Telus & spam issues.

        by jeffdammit ·

        In reply to Interesting

        We too, in Western Canada have experienced similar issues with email. We host a pop3 email server that we offer to customers in Western Canada. One fairly recent issue we have noticed, is that our ISP (Telus) has started blocking port 25 smtp outgoing traffic from computers in certain areas to try & curb mass mailing from infected computers. Problem is, they’ve done this without telling any of the affected customers, so we don’t find out until clients start reporting problems. They’ve also blocked all traffic in certain subnets, even to legitimate, non-infected systems. What we’ve done to get around this, is to have the clients change their email client settings to use the ISP’s (Telus) outgoing mail server, so that it will not be blocked. After we do that, business as usual.

      You are not the only one having mysterious e-mail problems, bkline posted this Tech QA recently and we are still trying to figure out what is happening:
      http://techrepublic.com.com/5208-6251-0.html?forumID=50&threadID=154626

      And nebheprura is having trouble sending and receiving any e-mail with his installation of Outlook Express:
      http://techrepublic.com.com/5208-6239-0.html?forumID=50&threadID=154159

      I took some time to search Microsoft’s Knowledge Base for any articles that may help your situation, but this was all I could fine. You didn’t mention what version of Outlook Express you were using, but if it is not at least version 5.5, I would upgrade it:
      OLEXP: IMAP and HTTP Messages Do Not Appear in Inbox
      http://support.microsoft.com/default.aspx?scid=kb;en-us;227928&Product=oex

      For a comprehensive look at TechRepublic articles published regarding Microsoft Outlook Express you can get the free compilation download, which has been downloaded over 31,000 times:
      http://techrepublic.com.com/5138-6249-729208.html

      So kherl, tell us, are you still having trouble or have you solved it? Either way, we want to know.

      I’m curious, is anyone else having problems with Outlook Express doing odd unexpected things?

        outlook mail delivery mysteries

        by chriswatson ·

        In reply to TR Resources for e-mail problems help

        The problem would most likely be the corporate email server/receiver, check its blacklists and it’s redirects and possibly how it resolves email addresses.

        It is not likely to be outlook.

        Collect relevant information on the path to and from one end and the other, you can then eliminate one thing at a time,

        Assuming OE is the Problem?

        by usaatca2001 ·

        In reply to Try this OE problems site

        Many replies are assuming that OE is the culprit here. That could be very misleading. OE is only the client. That is, it receives the mail sent by the server.

        To rule out OE as causing the problem, try another email client, such as Mozilla Thunderbird. I wouldn’t recommend Eudora, as it installs spyware that doesn’t uninstall when you remove Eudora. Another client will either work or fail just as OE does. If it does work, then OE is the problem. If the new mail client fails also, then it’s something else.

        If you can rule out the mail client, then work backwards to the failure point.

      In reply to EMAIL PROBLEMS HELP!!!

      I feel your pain. First I became locked out of my e-mail via a password,which just seemed to appear, so I lost my address book and everything. I made two new accounts, one is working but the other isn’t. Both accounts are EXACTLY the same, just different addresses. Very frustrating! And I’ve read everything I could get my cheeto-stained hands on and nothing has worked.

      Also, a few weeks ago people were getting copies of my e-mails without my knowledge. Apparently fired off via certain keywords, although there seemed to be very little consistency. This is likely some type of virus. I have also recieved copies of people’s e-mails without their knowledge. Very scary stuff. Be careful y’all!

        Prevent virus-based Sending

        by larry3500 ·

        In reply to Same Here

        We all receive email with viruses; most of us have an antivirus program that blocks most of it. But there is always the risk that some program ‘takes over’ your email client (Outlook, Outlook Express, etc.) and starts shooting out email to the rest of the world.

        My solution is simple; in the configuration for your account, indicate that there is a separate address for outgoing mail. That separate address is the same as your incoming mail, but without storing the password.

        This means you have to enter the password whenever you want to send an email message, but it stops anyone/anything else dead in its tracks.

          In reply to Prevent virus-based Sending

          The changes above will do little good preventing your computer from sending out worms if infected by a modern email worm. The newer worms have their own SMTP engine and don’t use the installed Outlook/Outlook Express client to propagate. The only way this can be stopped is if the mail server requires authentication.

      possible cause of email problems

      by mcs1 ·

      In reply to EMAIL PROBLEMS HELP!!!

      I have encounted this same problem. The good news was that each failed email that was sent, was also bounced back from a secure ISP filter. After contacting the remote, independent, ISP I was able to get them to unlock the filter that was blocking my email to one client. This solved the problem for me.

        Thinking somebody is fibbing

        by chameleon186 ·

        In reply to possible cause of email problems

        Think the ISP has gotten crazy with filtering and possibly has broken the server. Few months back I used to maintain a MX servers and there is a fine line with filtering between having a working and broken server. Some of the advanced servers have many mechs for trapping spam. First thing is make sure your MX records and RDNS are correct if so I can only say the ISP is BSing somebody to cover their over stringent tactics. A certain Aohell ISP kept lieing about why messages where not being relayed when infact the location of my MX was on their blacklist not because it spammed but merly because it fell into a range. After 3 months of bickering finally got it resolved…..Good Luck email is a royal headache these days because of these spamming a-holes

        Possible problems with your POP connection

        by daniel47 ·

        In reply to possible cause of email problems

        I have a friend who was having trouble with his Outlook, being able to receive, but not send. He didn’t get any bounce things just stayed in his Outbox. He worked long hours with tech support, and then by accident found the specific pop connections (in his case, those with a phone number ending in 0101) were not working correctly. He changed the pop he connected through and everything worked. Not sure which network those pops were connected with.

      Answer from Tech at an ISP

      by tfordii ·

      In reply to EMAIL PROBLEMS HELP!!!

      I good place to start would be find out if either your ISP or the other company/ISP that your sending to uses any SPAM blocks. I know from work experience that if your ISP or the sending party ends up on a program like SPAM Cop you may not be able to send to that address. My ISP blocks emails to known SPAMMERS, however we provide bounce messages.

      Additionally if the other address is an AOL address they have their own rules about blocking.

      Sender Issue

      by skingan ·

      In reply to EMAIL PROBLEMS HELP!!!

      You do not specify if the problem is isolated to a specific company. We had a problem about a year ago where we would not get any emails from one of our customers. It did not matter who in that company sent the email, we did not get them. The problem turned out to be on thier side and not ours. They had an e-mail router that was not forwarding any email to our address.

      More info needed

      by bitbucketboy ·

      In reply to EMAIL PROBLEMS HELP!!!

      Are the sender companies receiving any return message (undeliverable, etc)? Is their email to you actually leaving their queue? What is the SMTP “conversation” in their server log? Is it always the same companies? Do they have a common ISP?

      Does your company have a firewall? Which type? Did you say your machines have no antivirus? Scary.

      Have there been any changes to your network as of two weeks ago when the problem started? (However trivial they may seem).

      Have you run a DNS report (www.dnsreport.com)? Check to see that your mail.yourcompany.com has an A (address) DNS entry, and that yourcompany.com has an MX entry.

      rDNS is the point

      by flx ·

      In reply to EMAIL PROBLEMS HELP!!!

      Hi kherl,

      just have a look at http://www.swwork.it/approfondimenti/email_checking.htm
      (you have to translate it as it’s in Italian).

      The problem is that some of the bigger player in US has started to apply the rDNS rule, this is an RFC rule but still not a standard.
      And the problem fall here, lot of us, small player has to stay in the middle between customers and middle-little players or in-house servers.
      rDNS states that while you cannot do reverse dns of MX or A record and (deeper) if you cannot verify the sender, the email has to be discarded.

      So you end up not receiving email from certain people.

      While it is fast to fix the thing you will hit the wall while the other side is bigger than you and don’t want to listen.

      To check it just find the IP of the MX and the reverse loockup it, if you don’t come back to the MX name you’re out of luck if you want receive email from there.

      Best Regards.

      Check rDNS

      by ulatek ·

      In reply to EMAIL PROBLEMS HELP!!!

      Hi,

      As several people have mentioned, definitely check DNS for a reverse lookup MX record. If you’re using your ISPs DNS server, you may need to call them and discuss it with them. Here’s a great site for troubleshooting DNS issues –

      http://www.dnsstuff.com/

      Also, there are a few good alternatives to Outlook Express such as Mozilla’s Thunderbird. You can always install something else to rule out a problem with OE itself, but if you’re having the same problem on multiple machines, it’s most likely a reverse lookup issue.

      Turned out that the sending organization had changed their smtp server. The new server’s name was “essex”. Guess what…our email server filtered out any messages with “sex” in the header. Have them send a message to another server (e.g. Hotmail) and then look at the header information.

        by jeffdammit ·

        In reply to Check to see if senders ISP is being blocked

        It could also be that the specific domain or IP address has been blacklisted. One problem we had was when a laptop user got infected with 2 mass emailing trojans over the weekend. His default gateway is our proxy, which is the same as our email server. We come in Monday morning to find out that we have been blacklisted on 2 anti-spam sites & 2 customer’s email servers are denying access. Make sure that legitimate email from your email server sends through port 25 & all other outbound smtp traffic is being blocked.

      In reply to EMAIL PROBLEMS HELP!!!

      Hello, I notice you have “bell” in your addy. Just very recently my ISP bellsouth.net has changed security of in and out emailing and sent the following email:

      Dear Valued Customer,

      We are pleased to inform you that BellSouth will be upgrading its e-mail service this month to reduce junk e-mail or ?spam? on the Internet. This message applies to you if you use an e-mail client program to read and send your e-mails. Some examples of e-mail client programs are Outlook and Outlook Express. If you only use http://webmail.bellsouth.net, http:// home.bellsouth.net or another ISP?s Webmail program to access your e-mail, you may disregard this notification, because it only applies to e-mail client software.

      Most BellSouth Internet Service Customers already have their e-mail client program set up for this enhancement to work properly, but we ask that you check your e-mail client program settings to ensure that you are able to enjoy these additional benefits as soon as possible.

      This spam fighting upgrade to the BellSouth e-mail service requires you to make a small change to your e-mail client by July 13, 2004. This change must be made to each account that uses your e-mail client program. These accounts include any account you have that ends in @bellsouth.net as well as accounts from other ISPs, such as yahoo.com, msn.com, etc. The change is:

      Add additional validation to your existing e-mail account.

      Your e-mail service will also now require additional validation to promptly send your messages from the BellSouth network. We ask you to check the box in your e-mail properties that specifies ?My server requires authentication? and enter your e-mail account password in the appropriate field.

      For detailed instructions on how to do this, go to: http://help.bellsouth.net/blscontent/commoncontent/faq/smtp_desc.asp click on your e-mail client program and follow the steps to verify that your email client software is set-up properly.

      This change applies to all customers who send their e-mail with an e-mail client through the BellSouth e-mail servers at mail.bellsouth.net.

      If you do not ensure this change by July 13, 2004, after that date, you will be asked to enter the account password each time you send an e-mail. These changes will be required in order to send e-mail with our enhanced protection.

      If you have any questions on this upgrade, please visit us at

      http://help.bellsouth.net/blscontent/commoncontent/faq/smtp_desc.asp or contact us at 1-888-321-2375. Thank you for choosing BellSouth as your Internet Service Provider!

      Hope this clears up your problem.

        In reply to Email Probs-HELP

        It’s good to know that Bell is going to be pro-active and try to limit some of the spam originating from their networks.
        My ISP offers Spam Assassin as a free service that can be configured with both White & Black Lists.
        I think it’s great and I’ve blacklisted some major spam sources with it.
        *@swbell.net
        *@rr.com
        *@earthlink.net
        *@northnet.com.au
        and the list goes on to major ISP’s in Brazil, Denmark & France.

        On the other hand I’ve had to Whitelist everyone in my address book that uses the Sympatico ISP to prevent Mozilla from relegating their mail to my Junk folder.

      by david.frank ·

      In reply to EMAIL PROBLEMS HELP!!!

      Are you experiencing this over multiple accounts with your ISP or are you all downloading email sent to a single corp email address? Maybe someone’s Outlook Express config is set to delete messages from the server after downloading. Also, if your ISP has a webmail interface, you may try logging into that to see if the messages have made it to your Inbox on the ISP’s mail server.

      Never discount the human element

      by Mark W. Kaelin ·

      In reply to EMAIL PROBLEMS HELP!!!

      There are some excellent suggestions in this discussion thread so far, but it turns out the answer is rather mundane.

      I was curious about this e-mail problem, so I sent Kherl an e-mail to see if he had found the problem and fixed it. Here was his response:

      [b]We had 2 computers running a pop3 account with outlook express, one NT4 machine and one with XP. The computer with XP that I don’t have access to had another user account that normally isn’t used until someone logged on to it without my bosses knowledge. He did not log the account off and just switched users to the one he normally uses. The idle account was pulling off all of the messages so once I got into the office and saw that there was another account logged on the problem was solved! I wish my ISP and I would have thought to look at this the first day!!![/b]

      Perhaps Occam’s Razor applies: [i]”Of two equivalent theories or explanations, all other things being equal, the simpler one is to be preferred.”[/i]

      The problems caused by the human element in information technology are probably the most difficult to diagnose. And I’d be willing to bet that most of us have good stories to tell about the [u]human element[/u]!

      Troubleshooting

      by bill ·

      In reply to EMAIL PROBLEMS HELP!!!

      The first thing I would do, is to set up an account with Yahoo or Hotmail and ask the sender to forward/resend one of the emails that didn’t make it to this new address.

      If it doesn’t arrive there, it’s most likely a problem at the senders end.

      If it does arrive at Yahoo or Hotmail, ask your ISP to set you up a simple POP3 account on one of their servers, with an address like kherl@ispname.com and ask that company to again forward/resend that message there.

      Access that account directly… as in through their ‘web access’ feature if they have one and see if it arrives.

      If it doesn’t, there’s somthing in the setup for your company at the ISP, or in the senders outbound routers/firewall setups that has to do with your ISP.

      If it does arrive, then configure your OE to access that account on the ISP and see if it will download it.

      If it downloads to your OE… the problem then is in how your internal email server is dealing with the mail.

      This problem, like a lot of email problems, will take some ‘slicing and dicing’ to isolate the portion of the email ‘process’ that’s falling apart.

      Also… If you, your ISP, or the company that’s sending mail has popped up on the ORDB database, and someone in the path is subscribed to the ORDB service… the mail will be blocked as well.

      To resolve Open Relay issues, you’ll need to tighten up your email server to ‘relay’ only for your internal IP range and resubmit your email server IP address for testing.

      I hope some part of this post helps you resolve your problems.

      We had a problem with our filter software and its black list – one of our suppliers got put on a SPAMMERS list because their organization didn’t have security active on their mail server.

      Same thing happened here. We run Exchange in house through ISP#1. We have websites hosted by ISP#2. Suddenly, we could not receive any e-mail from anyone that had service through ISP#2. We could send to everybody in the world but could only receive mail from users that did not have to go through ISP#2. We discovered that because we “used to” run our mail through ISP#2, they had MX records that periodically were defaulting to the old MX that pointed to our old mail. Call and check the MX records of all ISP’s that touch or “used to” touch your mail.

      Based on what you stated I’d say it is a DNS issue. Someone else stated not so because DNS updates automatically. However, some ISP use BIND with DNS and the need to do a DNS Flush and reboot their DNS server. I know we had that problem when we switched ISP once and DNS was the problem until we had specific ISP flush and reboot.

      by rkg ·

      In reply to EMAIL PROBLEMS HELP!!!

      When I see something like this, I try to isolate it.
      Set up the Exchange client on a different computer, preferably with a different (older) version of the client software (outlook 98?)

      Send the same message from a different service (hotmail and yahoo accounts are handy for this testing)

      Send a different message from the same account (some spam filter acting up, maybe?)

      Send with notifications (delivery, read, etc.).
      Then, I try to read the header in the notofication to see what route it took, and what servers it saw.

      After this, you should have a better idea of the real culprit.

      Off the top of my head, I would also try to remember any windows or outlook updates you may have done recently, and try to find ways to evaluate them (have an old clean machine with outlook that has not received any windows updates since 2002?)

      Seen this before – here are some checks

      by deadly ernest ·

      In reply to EMAIL PROBLEMS HELP!!!

      OK, a few years back I had a string of similar problems with some clients I was working with and I was able to resolve them after a few checks. Had three different problems giving the same appearant problem. Final resolution of answer two took the client’s software experts two months to confirm the info I gave them about their server software. Have not checked all the other replies as I am currently on a shared 21.6 kbps service.

      First use a different mail client to log into your ISP mail server direct and see how that works, this will resolve the ISP fault concerns.

      Second if you have a distributed mail server system check the software versions and settings are the same. had a client with major troubles that turned out to be half the mail servers were version 4 and half version 5 and they worked slightly differently causing some messing up of headers at hand off between the servers, thus casuing e-mails to get sent to the bit bucket.

      Third have the people who are sending the e-mail to check the actual text in the addresses being used. had a case where the address got corrupted on the sender’s PC and it was now trying to send to a non-existent domain at .co instead of .com

      SBC/SWBELL email

      by gsporter ·

      In reply to EMAIL PROBLEMS HELP!!!

      Have you tried going in with the web email and checking your bulk (i.e spam) mail folder?
      SBC/SWBell just changed their email system and
      there is a chance the bulk mail filter got turned on.

      Thanks for your attention to this matter

      E- Mail Problem

      by pakkami ·

      In reply to EMAIL PROBLEMS HELP!!!

      1. check via internet explorer that ur mail is working or not.

      2. if u r using win98 or winxp check for any routine that is disturbing internet explorer u can check it by using .”MSCONFIG” command in “RUN” mode. check or any additional file that is running unnecessarily on ur machine and uncheck the command.

      3. after restart again check for MSCONFIG command

      I think this will solve ur problem.

      Is there any kind of error indication that the sender of the e-mail would get. You may have to contact them over the phone to be sure.

      I have had problems in the past where mailservers get added to a spam list and are prevented from sending mail to mailservers that are configured to use block lists.

      IT isn’t simple anymore.

      by jrusso ·

      In reply to EMAIL PROBLEMS HELP!!!

      Sometimes email messages get blocked because of the return address (such as when a reverse DNS fails). I’ve seen a lot of these that are transient – the rDNS can fail just because of packet loss caused by network congestion. In those cases, the same message will go thru if re-sent a few minutes later.

      Many messages are lost because the ip address of the source machine or of one of the relaying smtp servers is on some black list. Many servers are refusing anything passed to them directly from any dynamic address. One university actually blocks everything from adsl connections, even static-ip connections. ISP’s with lots of smtp servers are continuously fighting a battle with RBLs who blacklist a server every time one of the isp’s customers gets a virus. Until some customer notices ant tells the isp that a certain server is blacklisted by a certain RBL, nothing gets fixed.

      The amount of SPAM traffic has pushed many postmasters to back off on sending NDR’s. It used to be that when you couldn’t deliver a message, you sent a Non-Delivery Report back to the sender. Today so much email has fake addresses (spam and viruses) that trying to send an NDR often just results in more undeliverable messages clogging up your queue. At my agency, when an employee leaves the company, I’ll send NDR’s for a month ot two, and then just divert the messages to the bit bucket. Otherwise my server would thrash forever trying to send NDRs to fake addresses.

      So if you’re not getting any error messages back to explain the loss, you have to experiment until you can prove what’s happening. Then maybe you can shame someone into admitting what they’re doing. Get yourself an alternate address on another service (hotmail or yahoo will work). Have those who can’t reach your company email send a message to your alternate. Look in the headers to see the originating and relaying ip addresses, and look them up on some RBLs to see if one of them is blacklisted.

      If the problem gets serious, move your domain’s email to a different isp. Some isp’s periodically go through months of brain death. Sometimes it’s caused by a recent or upcoming merger. IT isn’t simple anymore.

      Missing Emails

      by deanyeo_43 ·

      In reply to EMAIL PROBLEMS HELP!!!

      I have this problem in Singapore too. In the last 4 weeks, I have been getting feedbacks and complains from users for the missing emails from external. Previously it was fine. So this would be the fault of my company ISP? I have reflect this problem to microsoft but they also can’t find anything wrong with that. Please advice.
