Things that are nothing special, e. g. using your own mail
server to deliver mails, is nearly impossible today if you're
within an address range of a provider that gives you dynamic
IPs. Spam and nastyness are usually problems generated by
others (not by those who set up their own mailservers). So
mails cannot be delivered. This hasn't been the situation in
the past, but due to approx. 90% of the amount of mails being
transferred being spam... you can imagine the reasons for this,
but "the UNIX people" have to suffer from it, while the "don't
care" crowd relies on someone else keeping the mail transfer
infrastructure running...

Another option is to forward outgoing mail to a MX of the ISP
that is not on a blacklist. The sendmail service provides an
easy means to achieve this: SMART_HOST. This does not cover
incoming mail, of course.
