[IMail Forum] Unable to send mail error

[Jeff Czyzewski]

I’ve set up a new Imail server. We are getting ready to migrate from Server A to Server B. I have 1 domain(IP) and 1 Virtual on the new server.   When I attempt to send mail through the webinterface on the new server I get a Delivery Failed error in Killer WebMail templates. Mail to any domain from the new server fails.   I’ve setup both servers(new and old) so they are identical. Even when I open up the relay for anyone I still cannot send mail.   Any ideas what I’m missing on the setup of the new server? BTW: I can receive mail on the new server. Just not send.   Thanks,   Jeff
