I'd advise you not to run your own company's mail server until
you've had some experience running one for a less critical domain
(say, a personal one). It won't cost you anything but your time and
effort to run your own server on a DSL line with a static IP (I
wouldn't bother trying if you're on a dynamic IP). That's how I run
my own mail server (and DNS for that matter).
It can be done on a dynamic IP, if you use a service like dnsalias.net to keep
your domain name pointed at the right IP. It only works well if your IP
rarely changes, though. If you have the type of connection where it changes
every few hours you're going to end up with a lot of delayed mail, due to DNS
entries lagging behind.
