I disagree.  Once spammers learned that using an MX left a log
trail, they began spamming direct-to-MX from dialups, DSL, and
cable.  Few people have a valid reason for not using their
provider's MX.

It would be interesting to see whether more direct-to-MX senders
are spammers or clued people running Unix at home.  I've noted
far more of the former than the latter.

Why do you not wish to use your provider's MX?  Security is not a
valid reason.  Reliability might be an issue, but the fact is
that you're lumped in with SMTP abusers; the filters that people
run hurt reliability.

You can always use authenticated relaying, or SSH in to your MX
and run Pine...
