Hey everyone, I'd like to create a little server running Ubuntu and postfix that would be a mail relay for a few other servers in our school district. For example, rather than configuring our Moodle and nagios servers to send their own mail, I'd like to point them at the mail relay and have it send the mail for them. This box would not need to receive mail, only send it. We run GroupWise for our staff email accounts, but it can be a hassle to configure other servers to send mail through GW sometimes. I started putting together a main.cf file for postfix and got this far (in addition to the other default settings): mydestination = $myhostname, localhost.$mydomain, $mydomain myhostname = bison mydomain = buffalo.k12.mn.us myorigin = $mydomain relayhost = monitor.buffalo.k12.mn.us # This is our nagios server Am I on the right track here? -Tim -- Tim Wilson, The Savvy Technologist Twin Cities, Minnesota, USA Educational technology guy, Linux and OS X fan, Grad. student, Daddy mailto: wilson at visi.com aim: tis270 blog and podcast: http://technosavvy.org
