Setting up mail servers is hard because email is a very old technology. What we do today with message queues, they used to do with email. The protocols are monstrosities from what I'm told and there are lots of moving pieces. The best thing to do is to find a solution that pretty much sets itself up and don't tweak the knobs unless you need to. Probably someone on here can suggest a nice solution. Also, being a smart programmer has nothing to do with skill in setting up servers, which is more of an Ops task. It's one thing to write good code, it's a completely different skill to walk through installation manuals and editing config files.
