I setup postfix on my ISPConfig server to use SMTP relaying using this link: http://www.howtoforge.com/postfix_relaying_through_another_mailserver . It worked like a charm.... EXCEPT: When I reply to an email I sent from the server it goes to the gmail account I am relaying through (as in I send myself a test message to another email address). Is there a way I can get around this? Rather than have the recipient change the email address it is going back to? Basically I am trying to find a way that I can send mails from my server (which is on a static IP with Comcrap) and it function just as a regular e-mail sever. Is there any other way to do this?
