Hi everyone,

Some friends and I are running our own mailserver on postfix.
Currently, our server is the main mail server for our domain -
org.mydomain.org recieves and sends all mail for mydomain.org.
However, I am about to get my own server, and I want my mail delivery
(to igor(a)mydomain.org) to go to the new server (new.mydomain.org)
instead, leaving all other users unaffected.

What is a good way to do this?

For bonus points, is there any way to make new.mydomain.org a backup
mailserver for orig.mydomain.org while allowing new.mydomain.org to
still deliver some mail locally?

I was thinking that my true email address would have to change, from
igor(a)mydomain.org to igor(a)new.mydomain.org. Then, new and orig could
be mx servers for the mydomain.org domain and new could be the mx
server for new.mydomain.org. Then I would set up orig to forward all
mail for igor(a)mydomain.org to igor(a)new.mydomain.org. does this make
sense? is there a better way?

Thanks,
--igor
