E-mail problems

By Jeroden ·
Hello all, new poster here, and I apologize for asking a question right when I get on here, but I have tried everything in my power to fix this.

I am having problems sending e-mails from my Exchange 2003 server. It is only to certain domains, so I am not sure if I am blacklisted or not. What are some steps that I should try to remedy this situation?

what is the undeliverable mail error message?

by sgt_shultz In reply to E-mail problems

Hi, what is the exact message you receive when you try an email to one of the domains in question.

Here is the message

by Jeroden In reply to what is the undeliverable ...

Your message did not reach some or all of the intended recipients.

Subject: Test
Sent: 4/30/2007 2:31 PM

The following recipient(s) cannot be reached:

'ristar5611@hotmail.com' on 4/30/2007 2:31 PM
The e-mail account does not exist at the organization this message was sent to. Check the e-mail address, or contact the recipient directly to find out the correct address.
<cmicsp.org #5.1.1>

I know that the address works because it is one of mine.

Does it ring a bell?

Did your server generate that NDR?

by Churdoo In reply to Here is the message

Is a hotmail server, or is one of your servers that generated that NDR? If it's your server, then your exchange org thinks it's responsible, or "owns" @hotmail.com, and is looking for that email addy in your own active directory, hence the failure.

If this is the case, go into RUS -- System Manager / Recipients / Recipient Policies / and check through all of the policies and see if @hotmail.com is listed in any of your policies, and/or any other of the domains that you're having trouble sending to.

Remove any email domains that your exchange server does not "own" and then go to Recipient Update Service and Rebuild the Domain and Enterprise RUS.

Give a few minutes or hours depending on the size of the org, and send a test message.

Got it

by Jeroden In reply to Did your server generate ...

That is what happened, it thinks it "owns" all of these domains, and it is a lot of them. How do you suppose that it started thinking that it owns these domains? Do you think a virus could have done this? I was told before I inherited this network, that there was a pretty big virus outbreak.

There's a reason

by Churdoo In reply to Got it

Not likely; I've never seen nor heard of a virus populating the recipient policies with domains.

I suspect that it may be related to the reason that your predecessor is no longer there and that you've "inherited" this network. And I'll go out on a limb and say that this probably isn't the first weird configuration that you've come across. :-)

Glad to have helped.

Still a problem

by Jeroden In reply to There's a reason

I gave it overnight to update, but it doesn't seem to update, I think it may be because of the replication problem, but I want to make sure I am deleting the policies right.

What I did was tested hotmail first. I went to policies, and removed @hotmail.com from the list. It was on two policies, so I made sure to get both, then I hit rebuild. The next day, I tried it, and it gives me the same message. I am gonna try to demote this W2K server and see if it makes it better

Errors?

by Churdoo In reply to E-mail problems

Are you getting any NDR's or errors of any kind or do the messages seem to go, and you get no errors nor NDR's, but the recipient never receives the message(s)?

Is it the same recipient domains all the time and every time?

Use the message tracking tool to make sure that the messages leave your Exchange Org. If so, then you may not comply with email sending best practices and may be blocked by anti-spam rules. Chances are if you are truly blacklisted, you'd know it by now, but individual organizations could be denying delivery due to lack of compliance and wouldn't necessarily notify you.

It's kindof a broad assumption at this point, so I won't go into the detail yet -- HELO/EHLO server name, reverse DNS, sending from static IP vs. dynamic IP, etc., etc.

Detail is what I would like to know about

by Jeroden In reply to Errors?

I posted the message that I receive in a previous reply, I hope that rings a bell with you and you are able to see something noticeable. Where would I check message tracking? Forgive me being green, I will google it until I get a reply.
