Slightly OT... Spam prevention the Bilano Way!

Bill Bilano here. Back to give you some updates on the situation at the
office. It looks like our new Sun's will be in to replace our heavily
infected Dell Xeon web servers. Port 443 traffic has finally died down
since we took all the bank's web servers off. We've only lost about 1600
customers over the whole thing so it's not a big deal to anybody of
importance. They don't need account information anyway, they are all
poor and know they are broke to begin with.
Anyway, I am writing you all about the ever growing problem of spam. I
get tons of spam evey day at the bank. I believe everybody here is
getting lot of spam. We've got one guy who is really upset about the
spam! His name is Ben and he works in the Account Retention department.
He's so mad at me he just flips me off whenever he sees me and, the
other day, he called me a loser. I can only imagine the amount of spam
he is getting to make him so mad.
So, since we're a bank and we're cheap, we have to get a lot of bangs
for our buck. The best thing we could do was to write a good spam filter
to soothe the savage executives and keep them from breathing down my crack.
I wrote this a week ago and have had it in full production use! It's
doing a great job and I have not gotten a single spam and I have lost
zero messages. Greylisting, so far, has been a great thing! So good that
everybody (other than Ben) has thanked me (which they already do at any
chance because, as I have said before, I am the reason they didn't get
hacked to hell and are still in business). So, since you all have helped
me out so much, I am giving a little back to the community!
I've gone ahead and written my first open-source app for you all to have
a go with! It is a free and open implementation of the greylisting spam
method as seen on greylisting.org for the wonderful and terrific Postfix
MTA by Weister "Ace" Venera!
I got it up for everybody to have a go at. See what you think, play with
it, use it, and peer review it so that it can, maybe, get included in
the next Postfix kernel!
You will need Postfix 2.1 and MySQL for this! Be sure to read the doc so
you don't screw it up like you always do.
You can get my app from my website: http://www.bilano.biz/
