PostFix+IMAP

[drag0n]

Can somebody help me with postfix and IMAP(COurier) RIght now I have PostFIx all cnfigured but I still dot unerstnd how hosting companies are able to do that header thing like right now I create a system user everytime I create a new e-mail accoun li domainname.username an Irestrict them from telnet and shell, but they stilllbeong to the server default domain so I dont know how I can send an e-mail from user1.mydomain and make it look at [e-mail] instead of [e-mail]? Is there a postfix admin that doesnt use mysql tables because I am using Berkeley db right now that can add vdomains for me and maybe make the directories so its a little moe organized or maybe someone can explain it to me, feel free to e-mail me:
[e-mail]
Any help is appreciated!

The "From: " and "Reply-to: " headers are completely under control of the mail client. The mail transfer agent (Postfix, in your case) adds the basic headers only when they are missing.

Configure the client software properly and you should not have a problem.

do you know how to conigure squirrelmail to do that?

SquirrelMail comes with a configuration script. The domain setting is on the "Server Settings" page of that script.

Alternatively, you can manually edit config.php and set the value of $domain.
