F12 - Postfix sending local mail

[dmarkd]

Hello,

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 root@domain.i.want due to the myorigin command. However, it is always delivered as root@computername.my.domain.

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.

Any help?

Well, I solved it so I figured I'd post in case anyone else struggles with this. The issue wasn't postfix itself but rather the fact that sendmail was installed and while it wasn't running, its configuration was interfering with the behaviour of the mailx command. I didn't have a need for sendmail so rather than wrestle with solving the configuration issues I just removed sendmail and things are working fine now.
