The trouble isn't getting the domain and setting up the email server behind it, the issue is maintaining the email server. I am sufficiently distractible (and I'm sure I'm not alone) that it's very important that my peripheral software/devices do not bother me. With an email server (or any other kind of server really, but email is especially bad), you need to pay attention to it constantly to make sure it is up, you are not on any blacklists (which you will get on by default for the simple fact that you are a new host), etc. You can of course set up all sorts of monitoring, but then you have to check that that is working. These concerns never really go away. You cannot truly let your email slip from your mind, because if it stops working ever you will miss emails (unless you use a relay, which is either external or also needs monitoring, etc) and that means that potentially things get closed that should not be closed, you miss things from the doctor/dentist, etc.
