Question E-mail FROM domain change -postfix


Switched to a Debian Testing server with Postfix. I used this postfix configuration on a slackware server with no problems before. The problem now is when i send a message from the server, the receiving party displays in the FROM field user@hostname.domain.com instead of the usual user@domain.com. I have the hostname and domain configured in the main.cf file. I am unable to figure out why the server hostname is inserted in the address. Not sure if this is postfix configuration or DNS problem.

Any help is appreciated.

Thanks

Do you have "myorigin" set in main.cf?

Quote:
# The myorigin parameter specifies the domain that locally-posted
# mail appears to come from. The default is to append $myhostname,
# which is fine for small sites. If you run a domain with multiple
# machines, you should (1) change this to $mydomain and (2) set up
# a domain-wide alias database that aliases each user to
# user@that.users.mailhost.

Yes. It is set to myorigin = $mydomain. No matter if it is set to $myhostname or the actual domain.com it still adds the server hostmane to the domain part of the e-mail address.

To be honest, I'm not sure if the myorigin works for me as I also use a generic map. This should fix the problem if you want to follow this route, although there must be a simpler explanation and solution.

To /etc/postfix/generic (assuming the path is correct) add

@hostname.domain.com @domain.com

postmap /etc/postfix/generic

and add/uncomment

smtp_generic_maps = hash:/etc/postfix/generic

in main.cf

Did a search for the generic file on the system but no results. I created the file and followed the generic(5) man pages. Basically did what you said billymayday. Tested and works. Thanks For the help.

IIRC I used to put the name in /etc/mailname on Debian. I haven't had a mail server running on Debian for a while so can't remember for sure, but "man mailname" leads me to believe that's still how it's done.

had hostname.domainname.com in /etc/mailname. Changing that to just the domain name does the trick. Thanks
