Hello Ryan,

You can install bogofilter either way (on the 2 outer servers or the 1
inner server).  It's probably easier to use the inner server as you
won't have to worry about synchronizing wordlists.

For initial training, it works well to feed bogofilter with 1,000 or so
ham and an equal number of spam.  After that, you should have your
users forward any classification errors to you so that yo_ can use
them to train bogofilter.  Alternatively, with bogofilter's tri-state
classification, you (as the administrator) could have procmail save any
messages classified as "unsure" and then you could make the spam/ham
determination and use them to train bogofilter.

Alternatively if you trust your users, you could have them forward
incorrectly classified messages to addresses like
"this.is.spam at yourdomain.com" and "this.is.not.spam at yourdomain.com" and
have a script to feed them to bogofilter.

HTH,

David
