Hi,

I'm trying to set up Postfix on one of our hosts to handle (among other things) 
outgoing mail.  We have several hosts in our domain (which I'll call 
domain.com).

The problem I'm trying to solve is that when I send a message, either to 
another user in our domain or to an outside address, the From: header of the 
message appears as

From: Adam Beneschan < a...@host1 >

(no spaces inside the angle brackets, I've added them to foil AOL), but I need 
it to appear as

From: Adam Beneschan < a...@domain.com >

main.cf currently contains

mydomain = domain.com
myorigin = $mydomain

and most recently I tried

sender_canonical_maps = hash:/etc/postfix/sender_canonical

where the last file was postmap'ed from a file that looks like

adam              a...@domain.com
a...@host1   a...@domain.com

(with other host and user names).  It didn't help.

What parameter do I need to get this to work?

(Postfix version is 2.2.10, on Fedora.  I set up the installation some years 
ago planning to finish it if a certain other machine ever died, which is what 
happened; if I can't solve the problem without upgrading, I'll do so.) 

Sorry if this is a trivial question, but the answer wasn't obvious to me from 
the FAQs or address rewriting documentation.

Thanks for any help,
                                    -- Adam
