I noticed that 2.5% of wt-en1's spam was hitting DNSWL_HI.  I asked him
about it, and it turned out that it was all cases where he had set up
forwarding from another server and not added it to trusted_networks
(he then deleted them).  I suspect this is true of others:

RCVD_IN_DNSWL_HI:
SPAM%
2.0785  bb-jhardin

RCVD_IN_DNSWL_MED:
 SPAM%
1.5012  bb-jhardin
0.3109  bb-jhardin_fraud

My corpora include messages from several different mail paths, and all of my corpora masschecks are done against uploaded corpora on the SA/Apache servers. How are we to provide trusted_networks data in that scenario?

(That's something I've been mildly curious about in the past - how the heck does the uploaded masscheck _deal_ with setting trusted_networks etc. for multiple disjoint corpora?)

I'm really curious how other people think spam from mailing lists should be
handled.

Should mailing list servers all be listed as trusted_networks?

As "trusted" means "does not forge headers", I'd say yes.

Or should spam from a mailing list be counted against the list server in
DNSWL?

Sure, it's spam. Do you want to whitelist a listserv that's relaying spam?
