Greg, as usual, you just plain don't know what the hell you're talking about.

SMTP works just fine with dynamic IPs, *IF* both ends are following the relevant
RFCs.

You don't follow them, so shit doesn't work for you.  That's your choice, and
it's yours to make; but stop pontificating that the rest of the world should
follow it, and that it's the technically sound choice.
