Controlling Spam to the NOC

[Jeff Workman <jworkman () pimpworks org>]

Hello,

Has anybody on this list figured out an effective way to eliminiate, or at 
least severely limit, the amount of spam that arrives in your NOC?  I am 
aware of solutions such as Spamassassin, Vipul's Razor, and the various RBL 
lists, but has anybody used one of these solutions, or anything else, to 
reduce the amount of spam going into noc@/trouble@/etc mailboxes without 
severely restricting the rest of the internet's ability to reach the noc 
via email for legitimate purposes?  Particularly in a NOC where it's quite 
possible that some of your customers are listed in the RBLs but still need 
to reach you.

-Jeff
