In the end I tweaked spamassassin to give a high score (3.0) to

there's still some headroom to take care of false positives (haven't
had many). I have a similar rule dealing with mail from obvious
dynamic addresses, giving it a score of 3.5
And that's the type of rule that frustrates me... I operate on a
dynamic IP,
but have an MX record that points at that same dynamic IP (and an SPF
record
to boot).
I suppose its folks with your kind of situation that make it a bit too
harsh just to reject dynamic hosts out of hand.
But as long as you send me clean messages they'll get through :-)
And the SPF lookup will be taken into account by spamassassin as well
and improve your chances even more.
