IN the last couple of months, spam which bypasses RBLs has been on the
rise. Of note is Yahoo. Some spammers iuse Yahoo's web interface to send
tos of spam. From the receiving SMTP's point of view, it is mail coming
from "legitimate" yahoo servers.

I ended up blocking large blocks belonging to Yahoo because I was
getting so much spam from them.
