General rules for training bayes

[Alex Regan]

Hi all,

I'm having some trouble with my bayes database, and thought it would be 
a good time to just rebuild it. I'm wondering if anyone has any good 
suggestions for the type of mail that should be used for training.

I understand individually-crafted emails would make the best ham, but do 
you train mail from mass-mailers? Staples? Facebook? Banks?

The main problem I'd like to avoid is the emails that are questionable 
as to whether they were opt-in and something the user actually wants, or 
those that are probably spam.

I have the database in a replicated mysql database for now. I'd like to 
go to redis, but it's not quite ready for distributed configurations, 
correct?

Thanks,
Alex
