Ok I posted here a month or so back about our email woes and received some good advice that lead me to my solution (also a couple of assholes answered, but this is Reddit so its expected). I have been working with our mail "server" for the past month and a half now and it just gives me headaches since it's so cobbled together and so disorganized that I finally made the suggestion, well insistence, that we blow away what we have, rebuild and move forward with a much cleaner and more importantly, documented mail solution. I have been looking at various solutions and wanted to see what the community's suggestions would be.
My environment: CentOS 5.4 Most outside emails currently being handled by Gmail and being pulled in using a fetchmail file. (we can create an address locally and it will route mail from the outside such as a jobs@xxxx.com and point it to an internal user for delivery) Internal emails routed locally and not handled by gmail. Dovecot responsible for delivery to the EU. Outlook client pulling from server over a SSH connection created by an additional program so we map it as 127.0.0.1 for SMTP and POP3.
I was thinking that the choices we have are simply ditching our internal server setup and setting up a relay on our server so it sends and receives all messages from gmail, or rebuilding our internal mail server so it is clean and trackable. I have been looking over dovecot, sendmail, and postfix. So far I am starting to see the way they can tie in with gmail, but still fuzzy on the details. What suggestions would anyone here have since I am not really seeing much as far as mailserver tie in with gmail in the documentation that I have been reading.
