No, it's a SMTP server, meant to receive mail on port 25, for example
from cron. You could put it to good use to relay mail you send to your
SMTP server (gmail or ISP), assuming you don't use webmail only.
cron can do without a MTA now and if you don't ever read root's mail you
can get rid of it, but I'd rather recommend reading root's mail
You could also replace it with a forwarding MTA, that doesn't run as a
daemon, if you don't mind sending root's mail via the internet.

This one is very good for troubleshooting.

anacron is useful if your machine is not on all the time, especially
during the night, when most cronjobs are set to run.
atd is useful if you want to schedule one-time jobs, unlike cron, which
is for jobs which have to be repeated on certain intervals.
