If you are a residential customer:
1. You probably don't have a clue what ahy of this means.
2. You have no need to run your own mail server.
3. Your AUP (at least for every ISP in the US who's AUP I am familiar
with) prohibits you from running an servers.

My experience as a residential customer (in Germany): No ports are
blocked, neither coming in nor going out. No prohibition against
running servers. When I first set up things at home, I of course tried
to send email directly from my cluster, which sometimes worked. Often,
it didn't. The reason was that I had a volatile IP address which was
blocked by the recipient (because it was in a block of volatile IP
addresses). This was done because it stops a lot of spam, and I later
started doing it myself. My solution: send email through an SMTP relay
server run by the same person who handles my dynamic DNS
( http://www.dynaccess.de/ ). Since the maintainer takes care that no
spam is sent through his server, no-one blocks it. (His terms and
conditions also specify a hefty fee for anyone trying to send spam
through it.) I do have to pay a bit more than I otherwise would for
this service, but the cost is negligible compared to, say, the cost for
the electrical power to run my cluster.

If everyone did this, there would be a lot less spam. One way is for
folks to block email from volatile IP addresses, forcing the senders to
send it through a trusted, white-hat server. The other would be for
ISPs to block it except through a trusted server. This assumes that the
ISP runs a mail server himself.

In my case, I wouldn't like this solution, but prefer to send through
the server at my dynamic-DNS provider. Why? Because it is IP-based
(he knows my IP because he handles my DNS). My ISP (1&1) requires
either my official email address with them in the From: header (not
something I want, since I might not stay with 1&1 forever) or SMTP
authentication, which (at least my version of) HP TCPIP services for VMS
cannot handle. In principle, of course, my ISP could do the same thing,
since he knows my IP address as well (my router gets it via DHCP).
