Hi,

I have a machine with two IP address. x.x.x.10 and x.x.x.11

Postfix accepts mail sent to either IP, but ONLY SENDS MAIL OUT FROM
x.x.x.10

I would like to have it still receive on both x.x.x.10 and x.x.x.11
BUT SEND MAIL OUT FROM x.x.x.11

Can someone help me figure out how to do this??

Below is what I have in master.cf.

Thanks in advance.
