Own postfix smtp server as relay for Google Apps Premier Edition
Posted on 2009-02-11
Hi, I have a domain set for use with Google Apps and, apart from my main email address, I also use with gmail another email address with different domain.
Using the "send email as" feature as it is, if the person who receives my email uses Outlook, (s)he can see my original email address which instead I don't want to be shown.
Similarly, my original address is clearly visible in the headers.
Following some research, I have found that by upgrading to Premier Edition (which I have done already), I could tell Google Apps to use my own STMP server.
This should remove the sender header and therefore my original email address should remain hidden.
I have a VPS with Slicehost, with Ubuntu 8.04, and postfix is just installed but not yet configured.
How shall I proceed in order to use this postfix server as relay for my Google Apps accounts?
I don't really have much experience specifically with these things, but I can easily understand and follow instructions, so I would appreciate if somebody could illustrate the process in steps.
Many thanks in advance.
