SMTP relay problem

Posted on 2007-10-01

I have both Exchange and POP3 e-mail settings in Outlook 2003. I can send and receive mail fine, but when I reply I get a SMTP relay error 550.5.7.1 and it is defaulting to send through the POP account. If I specify the Exchange account, it replies fine. How do I change this setting and only allow send replies thru the POP account?

    Does it happens only when you reply to ppl within your organisation or without your organisation or both?

    I believe it is only when I reply to messages outside of my domain.

    I don't think you can. Exchange account use a different protocol MAPI. And it all gets tied in with the account created.
