Re: [LUG] Different IP address for mail

 

If you still have a mail server at Server 1, and you want user's mail
sent to Server 2... Easy, and nothing to do with ip addresses.

Assuming your user's name is freddy, and you want his email sent to
freddy@xxxxxxxxxxxxxxxxxxxxx

On server 1 where mail normally arrives, edit /etc/aliases

freddy: freddy@xxxxxxxxxxxxxxxxxxxxx

Been using this a lot recently when migrating users to another server.
Of course they need to use their new address as a reply-to, but this
ensures no mail gets lost. And you don't need to run any additional
program to fetch or push, but when you do use this to migrate
somebody, imapsync is the bunny. (Complicated legal status, but the
author has the latest versions on his site if you google around)
