I can receive but not send e-mail from outlook 2003. I get instanly messages like "553 Relaying is not supported"

Hi. I cannot send messages from outlook 2003. It keeps givving me messages like "553 Relaying is not supported" And it only seems to be doing it when I send it outside my domain. So it does not do it with every e-mail address.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Greetings, iaposner.

Are you connected to an Exchange server?  Is Outlook configured for just one account?

Cheers!

Hi, no I am not connected to an exchange server and I am not sure about the second question. I do have outlook look at two accounts, so I guess it is configured for two acounts.

Relaying occurs when you try to send mail from account A through the mail server for account B.  Since there is no account A on B's server that server cannot authenticate account A and would have to relay the mail.  Most systems don't allow that since it would allow anyone to send as anyone else.  With Outlook configured to talk to two accounts one account is the default account.  Any message not specifically told to go through the second account will go through the first account.  The solution for this is to click the "Accounts" button on the toolbar in a new message and select the correct account for messages that should go out through the second account.

Greetings, iaposner !

1. Register an important send/receive library file.  Go to Start > Run and type regsvr32 inetcomm.dll

2. Check if antivirus email check is slowing sending and receiving.  Disable it.

3. In the account settings, Advanced settings, change the server timeout time from 1 min to 5 min

4. Check if outgoing mail server authentication is required. Select that option in account settings and use same settings as incoming server

5. Your ISP may be blocking port 25. Try using alternate port 587.

6.  Check with email provider Tech Support to determine if server is having trouble.

7. See this troubleshooter for not sending

At the end I ended up using the in comming server from one provider and the out going server froma a nother. And this seems to work (for now). I like to thank all for your support.

laposner,

So your ISP is blocking port 25 to other servers than itself?  Thus you had to use your ISP server to send?
