You can use a mailserver without a persistant address in one of a few
ways. One is to run fetchmail on it to fetch your mail off of whereever
it actually gets delivered, like your ISP's mailserver. For outgoing
mail, you either use them as a "smart host" or you hope that they allow
you to send mail out directly from your machine (which some don't and if
they do then some people think you are a spammer because you come from a
dynamic IP address).

Another could be to use some kind of dynamic DNS setup, like dynodns.net
or dyndns.org or something. I haven't tried this in years, but some
people have limited success with it. Some dynamic DNS providers will let
you use their mailservers as a secondary or something.

I have always thought this this post:

descrived a rather handy way to move mailboxes from one mail server to
another. I guess it depends on you having more than just POP or IMAP
access to the old mailserver, though. Otherwise, I guess I'd use
fetchmail to pull them all off of the old one and feed them to the new
mailserver.

Since I started running debian, I learned postfix and have found it to
be better in some ways than sendmail, but in some regards this is closer
than I like to venture to the "religion and politics" threshold I like
to see on this list.

Hope it helps!
