Hi all, Ive done this before but the solution alludes me now. Can someone please remind me how to change the default Redhat behavior of root email being sent from root@server.domain to root@domain. It's something in sendmail.mc from memory.
From memory, Sendmail will default to user@host if there's no fully
qualified domain name for either localhost or the system's 'base' IP address in /etc/hosts.
There's probably a more correct Sendmail approach too. Checking /etc/mail/sendmail.mc
LOCAL_DOMAIN(`localhost.localdomain')dnl
Looks a likely candidate.
Or if you're running postfix...
in /etc/postfix/main.cf uncomment this line:
#myorigin = $myhostname
so it looks like this:
myorigin = $mydomain
Then restart postfix. That will affect all mail from the machine so instead of getting mail from root@blah.mydomain.com, it will be root@mydomain.com. It's been 7 or 8 years since I've fondled a sendmail config so I don't recall off the top of my head how to translate that into an m4-ism.
Hope that helps.
Cheers,
