I'm trying to configure my postfix installation on Fedora 12 to set the domain on local mail being sent from my system. What I believe are the relevant configuration parameters are set to this:
myhostname = computername.my.domain
mydomain = domain.i.want
myorigin = $mydomain
I'm expecting with this configuration that when I send mail as root, it should show up as firstname.lastname@example.org
due to the myorigin command. However, it is always delivered as email@example.com
I've searched around and found different information on virtual alias maps and other solutions which should solve this problem, but none has worked for me. Beyond that, I'm not hosting multiple domains on postfix, just the one domain I'm trying to send mail as.
