Running your own mail server certainly has advantages. But, it is typically more than just Exim. You'll need to install something for IMAP access. Or, if you want web mail, something for that. And, even if not right away, eventually, something to deal with spam...it will come soon enough. Also, those pieces tend to require other pieces (backing database engines, etc).
Similarly, you have to read up on things like domainkeys, spf, IPV6, MX records, PTR records, firewalls, etc...then implement them.
If you also want to run a ZNC host or personal webserver, it's a pretty good deal.
Your concerns about self-hosting are fair, but I would encourage you to take a leap of faith and do it anyway. Exim doesn't require any maintenance-- if you get it setup right in the beginning, you'll never have to touch it again.
