I see this a lot also and what I see causing it is accounts on my servers
that don't opt for spam filtering and they have their accounts here set to
forward mail to their yahoo.com accounts - spam and everything then gets
sent there - they complain to yahoo.com about the spam and bingo - email
delays from here to yahoo.com accounts....
