Subject: Innovative Host Blacklisting Idea
I'm trying out a new idea for blacklisting hosts. I have
several email
servers for processing spam. These servers service my lowered
numbered
As others said, not a good idea.
Don't bother BL isting them, if they hit your dummy mx record, they die,
don't retry, and have in effect blacklisted themselves.
What I see happening is that they are hitting MX randomly. So some times
they hit a good server and sometimes they hit the trap. Once they have
hit the trap several times then they are blacklisted in my hostkarma
blacklist and if they hit a real server they are rejected at connect time.
On my servers less than 1% of all email attempts make it as far as spam
assassin. This reduces it further.
