Beat me to it - not only that, but most ISPs will helpfully add the
dynamic IP they gave you themselves to spamhaus the second you light up
a SMTP host on their connection which is seriously going to crimp your
style going forward.

So you're going to need a SMTP smart relay service at a minimum, and
your ISP probably won't provide one that doesn't "helpfully" re-write
your message headers on the way through. Plus you shouldn't trust them
anyway.

Don't let us discourage you Julian - setting up email servers isn't that
difficult and it's fun/educational so carry on obviously. There are just
a *lot* of additional issues involved with mailservers that you're
probably not aware of...
