I'm still considered a newbie when it comes to Linux. My current project is building a mail server. MY setup is this: I have a Co-Lo server at a friends location and it will be my companies web server. It is running great with Apache, PHP and MySQL. I am also setting up a mail server which will run in-house. I am currently building it. I am also going to use this server as a test web server for building my site before I upload it to my web server that is actually online. Sooooo........ I need to setup this mail server but I am not familiar with setting up sendmail. Also considering it will have a completely different IP and will run on the same IP as the internet all the users here will use I assume the MX Record will have to have a port so my firewall will port-forward mail to the server (I hope that makes sense :¦)
My question is, does anyone know a good tutorial to get me going for this setup? I found a couple tutorials but they just confuse me. Also, do I need a DNS running? Or, could I use a company liek EasyDNS who offers DNS with the domain hosting.
Thanks for your help :)
(If you need any other info please feel free to ask)

OK, I freely admit I'm biased here. However, you may want to consider looking into alternatives, such as [url= [postfix.org...] or Exim [exim.org]. The config file uses actual words! =) (and yes, I know about sendmail.m4. It's a joke. Run with it. ;) )
However, all that takes a back seat to:

Make sense? Sure. Possible? Negative. DNS groks IP addresses only; no ports (and just as an FYI, note that MX records can NOT be CNAMEs). BTW, if you want to read up on DNS, I recommend the O'Reilly cricket book [oreilly.com]; there's also quite a bit of documentation and a good number of links at [bind9.net ].
I did try postifx but found it buggy and also found there to be no help available for it - even the official mailing lists arent setup properly, I subsequently dumped it and have been very pleased with exim.
exim has also (deservedly in my view) just won the mailserver review in Linux Format magazine, beating postifx, sendmail, qmail and several others. very good writeup.
