In case you don't know, the BMS ("Blacklist Mastering System") is a way to
check against many different blacklists without the overhead of DNS lookups.
We normally implement this at the tcpserver or SMTPD layer, however we have
had requests about using it at the Spam Assassin Level, instead of
traditional DNSRBL style lookups. But, as using it at the Spam Assassin
Level is not how we normally implement, and our resources are stretched thin
at the moment, if someone wants to take this on for the good of all Spam
Assassin Users, by all means contact us.
Basically, you trade off 500Mg of harddrive space for very effecient lookups.
(.004 secs) Now you can lookup against as many lists as you want, and you
don't have to worry about network outtages, DNS Caching, DOS attacks at the
blacklist provider or any of that.
If there is interest, we can help any party who wishes to try this out. The
Client Programs are freely distributable.
It can work as a drop in replacement for rblsmptd, or you can use it by
calling the 'bmslookup <IP ADDRESS>' directly.
For more information, you can check out the homepage at
http://www.linuxmagic.com/products/bms, however you will have to excuse that
the developers have just uploaded the new site, and are in the process of
packaging the system for different OS's..
