Why Black Lists?
We have started using outside "blacklists" to handle incoming spam for several reasons. The biggest
reason is that our mail servers and filters are spending more time processing spam mail, than legitimate
mail. This means massive mail delivery slowdowns, delays sending and receiving mail, and heavy processor
and ram load on our machines.
Another reason we have resorted to blacklists is because very little spam makes it through these
filters (and any that comes to our spam traps, gets immediately reported to
SpamCop ).
Of course, there are bound to be some "false positives", and we deal with these on a case by case
basis. However, nearly everything we block appears to be spam.
Below are listed the current black lists we use. They are loaded and check in the order they are listed.
