I'm running Postfix server under RHEL-5.1.
Early I was having one base domain (eg. domain.com)..
Now I have created a virtual domain say sub.domain.com. And for this virtual domain I have mapped linux user accounts under /etc/postfix/virtual. So when outside users are sending mail to firstname.lastname@example.org
its reaching my Postfix and dropped into the respective user mailbox with help of virtual user mapping. But from this mail id (email@example.com) if I'm sending mails to other users in destination mailbox the from address is looking like this:firstname.lastname@example.org..
So now I just wanted to know how to specify the myorigin parameter for the virtual domains under postfix..
Kindly help me with this issue..
Thanks a lot..
Update:Guys, now I found that while receiving mails to that virtual domains user account also in the header "to" address is renamed to base domain name....
