    Right. I was referring to the fact that SA/CRM114 'tag' mail headers 
    with a spam index, and then let user-side software deal with it 
    (procmail) rather than rejecting mail outright - the RBL approach - at 
    the MTA level.

Oh, I get it; when you wrote

    ... of which, I just found about 1000 fall in one of three roughly 
    identically-headered pieces of virus/spam mail. When migrating lists, 
    I'd like to hook automatic virus scanning into the MTA ...

you didn't mean the latter sentence as a solution to the former
(i.e. the size of our queues), but rather to the downstream problem
(i.e. the spam in users' mailboxes) it points out.

It's true that I don't really need any customization of my spam filter
beyond perhaps what numerical threshold I use.  So system-wide
tagging, if it makes learning more effective or even just saves
resources, is a good thing.

Other thoughts?
