new anti-spam measure heads up

[Dan Brosemer <odin@svartalfheim.net>]

Enter greylisting.

We now reject all mail from any host the first time we see mail from that
host with a temporary failure and keep track of where it came from.  A real
mail server will retry in 30min to 2hrs.  A spam drone or an email worm
won't.  When we see the retry, we accept the mail.

This means you may see a short delay in legitimate mail from each new person
you correspond with the first time they send you a message.  Subsequent
messages will be passed immediately.

This has stopped 30 spams in the last 4 hours without any training.  Nothing
else I've implemented to date has been so effective!
