Subject: Slightly OT... Spam prevention the Bilano Way!

Yo Dudes!

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/
