Info on mail server
I need to figure out how to set up linux to be a mail server. I know sendmail is the most common service but I need to know about Postfix.
Does anyone know where to go to get the best info on how a mail server works?
What steps are needed to set it up and trouble shoot common problems?
I know linux. I just don't know sendmail or postfix.
Can't seem to locate the HOWTO for Postfix.
