Postfix $myorigin issues
 

I have:

myorigin = $mydomain

But instead of mail showing up as coming from user@mydomain.com, it shows up as user@localhost.mydomain.com. The $myhostname parameter is set to a different hostname.domain.com, but my server's hostname (outside of Postfix) is localhost.localdomain. This box is behind a router that is simply doing port forwarding to the NATed mail server.

Any help would be greatly appreciated. I am somewhat new to Postfix.

What is the value given for $mydomain in your config file?

And how are you sending emails out? You know you can change your outgoing mail address in the client you use to send mail..

$mydomain = domain.com

I am logged onto the server using squirrelmail. I haven't set it up on a software client yet.

Once you mentioned that, it hit me that it might be squirrelmail causing the problems, so I took a look at the config.php, and this section stood out:


$domain = 'localhost';
$imapServerAddress = 'localhost';
$imapPort = 143;
$useSendmail = true;
$smtpServerAddress = 'localhost';
$smtpPort = 25;

Is that where the problem is at? If so, what should I change it to? it doesn't say localhost.domain.com, it just says localhost. Should I just leave those as empty ticks on the $domain line?

OK. I removed the $domain 'localhost' entry and just left it as ''
Then it wouldn't send mail at all. So I just changed localhost to domain.com (for my domain) and it works perfectly now. Thank you for your help trickykid.
