For thse of you who want to get some spam reduction and help me harvest
viruses for my blacklist here's a trick you can do.
Set your highest numbered MX record to tarbaby.junkemailfilter.com
Any connection to that IP will get a 451 error after the DATA command.
No good email will be lost. But virus infected spambots often spam the
highest numbered MX records first and I can get useful data for my
blacklists. You are also welcome to use my blacklists further reducing
your spam. Here's how to access these lists.

Here's what I'm doing.
I'm looking for reverse DNS. Looking at if they close the connection
with a quit even after some short delays. Looking at the HELO and if
there's anything screwy about the from addresses or recipients.
Generally I can detect spambots the first time they try to spam. This
helps catch them sooner and everyone who uses my lists get the benefit.
Of course you have to trust me, but I've been around long enough that
everyone knows I'm a spam fighter. Here's how you set up your MX.
10 mail.yourdomain.com
20 tarbaby.junkemailfilter.com
You lose some spam - I gain some data. Everyone can feel free to just
use it.
