How to change ( masquerade) shell user name when sending mails via Postfix

saagar · 12-31-2011, 10:56 PM

Hi Happy New Year to all,

My query is as follows:

In my server, where postfix is running, I have a shell account as
sagar, I actually wanted to be seen by the world when they get
mail as "premsaagar@MyOriginatingDomainName.com".

So, I used the canonical_maps in /etc/postfix/main.cf as follows:

Code:

canonical_maps=hash:/etc/postfix/canonical

Then, in /etc/postfix/canonical :

Code:

sagar   premsaagar

then, from command line:

Code:

postmap /etc/postfix/canonical
/etc/init.d/postfix reload

When my friends receive my mail, it appears to them as:

Code:

from:	 sagar premsaagar@OriginatingDomainName.com
to:	 Receiver'sName@gmail.com
date:	 Sat, Jan 31, 2011 at 8:33 AM

It is working fine as far as username@domain.com, but I dont want the name "sagar" there ( that is my shell account name) How can I masquerade in such a way that it appears as premsaagar and not sagar?

Please help

I just had a very similar issue. I wanted to masquerade my shell account when sending mail via a script to my customers. Unfortunately, I'm not sure how you're sending e-mail so I'm just going to tell you how I got my issue resolved:

Code:

$ echo "This is a test." | mail -a "From: \"Ray P.\" <vertigoray@mailinator.com>" -s "Test" you@mailinator.com

Hope this helps!
