Help: In Outlook 2k, when I send mail, I receive the following error message
'the message could not be sent because one of the recipients was rejected by the server. Server Response: '550 relaying to prohibited by administrator'.(Account ''abc.com' SMTP Server: 'ABC.com', Error number: 0x800ccc79)
Note: I am able to set up my email account on the server and on the client 'OUTLOOK', I choose Tools, Accounts, Add, entered my name, my SMTP and Pop 3 were abc.com and my account name was jdough@abc.com. Even when I changed the account name to jdough, it still doesn't sent the word attachment. In the word doc, all i typed is 'this is a test email'

You can't get around this. The email administrator has set this restriction as part of a policy either to stop email at the abc.com address or stop attachments for better security. Attachments do contain viruses and it is not uncommon to find that they are prohibited on some email servers.

Thank you much for your input. This didn't help as I am the emai admin. I have a web site hosted by another company where I have full access to create email accounts etc. Further, mail sent from the server goes out w/out a hitch.
A work around was to input my ISP's email address (call it mail.isp.net) in the smtp field. This allows deliver of the mail w/out messages, though somewhat slow. I don't think I should have to do this as it worked for 1 wk without.

Your mail cannot be sent because of Simple Mail Transfer Protocol (SMTP) relay blocking
The problem can occurwith the following configurations
1)You are logged on to a local area network (LAN)that has an Internet gateway,and your attempt to send e-mail therough an Intenet service provider's(ISP) SMTP gateway
You are logged on to an ISP and attempt to send e-mail through another ISP's SMTP gateway
Contact system administrator
Ref:KB article Q214402

Possibilities:
In your account properties, go to the servers tab and click on the "my server requires authentication" checkbox
or
check your pop3 and smtp addresses. Usually it will be mail.abc.com or pop3.abc.com and smtp.abc.com (your Yahoo addresses are pop.mail.yahoo.com and smtp.mail.yahoo.com) although you seem to be getting through.
Hope this helps.

Contact your ISP and ask them. Isn't this one of the reasons you don't have your own web server?

You say that you have full access to create email accounts. Wow what an achievement. Every ISP will give such permissions to at least one person at each company. Other wisethey will be waisting time to just create email accounts. What you don't have permission to do is configure the SMTP options, like permiting or prohibiting relaying for which you will have to contact your ISP and tell them that you get an error: Relaying is prohibited

Are you mailing through an Exchange Server or IIS SMTP. If you are mailing through Exchange, you need to add your domain name abc.com to the Internet Mail Connector property page "Routing" click on Reroute incoming SMTP mail, then click add on the Routing box, add your domain. If that is already setup and you are using SP3 or SP4, click on the routing restrictions tab, if you have "Hosts and clients that authenticate..." checked, this is good it just means you have to change one setting on your POP3 account setting in Outlook.
Goto your account properties in Outlook or Outlook express, on the servers tab, down at the bottom is, 'Outgoing Mail Server', and my server requires authentication, check it and leave the defaults as it will useyour logon credentials. If you are using IIS SMTP, there is a relay restriction tab in the smtp server properties. check there.

Hope this helps.

do you have a static IP assigned for your Internet?
If not, the ISP may have aquired a new block of IP addresses. This can make the server think that it is being asked to forward a message that was sent by itself. Most ISPs have relaying such as this restricted.
The only thing you can do in this case is bitch at the ISP and hope they get their addresses resolved.
