If you run mail service elsewhere, port 465 (SMTP over SSL) and 587
(/etc/services calls it submission, I've usually seen it used for
SMTP+TLS) are good and relatively common alternatives. If you provide
mail services, you should probably have these open.
I've never been a fan of running any type of service on dsl/cable
service. The burstable bandwidth (even if you DO get 1Mbit/s upstream)
sucks, connections are frequently unstable, IP changes cause outages
etc. I'll host things that don't matter, like my MRTG graphs, make
VNC/SSH available... but I wouldn't host anything I count on, like
