email auto greylisting

[Mike Davis]

I have installed a new anti-spam mechanism on my system that will have a
small initial effect on how emailing the list works.

Basically what this system does is initially refuse your email, but it's not
a full reject, it just drops without receiving. Which in theory will cause
your email server to attempt a resend at some pre-determined time. This
time varies based on the email server settings. On the second attempt the
email will be accepted and your address added to our "grey list", and future
messages will be accepted on the first attempt.

I just wanted to let everyone know about this because the first time you
send an email to the list it might take an hour for it to show up, and this
is why. The purpose behind this if you're interested is that most spamming
applications do not attempt to resend a message, they work on a hit and run
principle. While legitimate mail servers will attempt to resend a message
after the initial failure.
