[Mimedefang] OT: Auxillary Spamassassin Rules?

[John Barton]

Greetings,
I currently run about 6 mail servers with about 25,000 accounts total 
across all the systems. I am getting a lot of email spam getting past 
the standard SA rules, and I'm considering using some of the 
supplemental rules that are available. I have started using RulesDeJour 
to keep a small set of additional rules on each system, and I am curious 
what rules, if any, that other people are using on fairly busy servers 
to help increase the amount of spam being detected.

Also, I was considering implementing baysian filtering, but my current 
setup would require a single bayes database for the whole system. I have 
read through the archives and seen it mentioned, but am curious about 
people's experience running a site wide bayes setup. I know it isnt as 
good as per user setups, but is it agreed that it is better than no 
bayes system at all?

Thanks to everyone for their help on this mailing list!
