No, it's not a big deal. The only maintenance I do is to try to improve
my anti-spam measures, and that's probably less than half an hour per
year. *After* the mail server was set up and running properly, of
course, and even that doesn't take much work.

*If* you have a static IP address and your ISP is willing to keep the
CIDR block containing it off of blacklists (some ISPs don't care). It
can allegedly be done with a dynamic address, but you not only have to
keep the MX->A record updated, but also the PTR. You may not even have
control of the PTR on a dynamic address. It's more to go wrong, and
there is a chance of delayed mail whenever the address changes. Also,
some mail servers try to identify dynamic addresses and reject SMTP
connections from them. 

If you have a dynamic address, the only safe way is to send through a
smarthost with a good reputation, and many ISPs do not provide them
now. Also, you lose logging of sent mail, which is one of the reasons
for doing it yourself.
