actually, almost none.
the number of geeks who want to run their own mail server from a dynamic IP
address is vanishingly small. the number of false positives from blocking
dynamic IPs is not just lost in the noise of all the spam and viruses coming
from dynamics, it is completely indistinguishable from noise. far less than 1
in a million messages.
a very small price to pay to block an enormous quantity of spam and viruses,
especially when those legitimate mailers who are affected can, if they could be
bothered, work around it quite easily and cheaply.

good for you. your server, your rules. sounds like a stupid thing to do, but
you are entirely within your rights to do so.
