Postfix/Dovecot WAN Issue

[LordJ]

Hey Guys,

I am able to send and receive internally with my new email server. Also I can send mail to the outside world but if I do a reply, the message is sent to the old email server. Even when I shutdown the old email server messages just get a bounce back. What else do I need to configure to enable the new email server to receive emails from the outside world?

Thanks

You must change the MX records for your domains so that they point to the new server.
