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:

2.0785  bb-jhardin 
0.3802  kgolding

Interesting that I showed up second on this list.  I found a bunch of stuff
I'm not happy with.  One of them was an interesting spam that showed up on
a private mailing list, apparently the result of a trojan or something, so
I thought it would be good to feed it to razor, spamcop, DCC, etc.  But it
didn't occur to me that I'd also be reporting the mailing list server,
because I don't have it listed as a trusted relay, because I generally
don't report spam from mailing lists.

A bunch of them were from old spams I got from the
[email protected] mailing list.  I ended up just removing
my old spam from mass checks, based on the log-grep-recent recommendations
on http://wiki.apache.org/spamassassin/RescoreMassCheck - 6 months for
spam, 38 months for ham.  (Surely that 38 was meant to be 36?)
I'd like to get that age filtration into auto-mass-check.


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?

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


Of the 108 spams since October 19th that I'm now running through
mass-check, the DNSWL hits are:  0 high, 2 medium, 1 low, 25 none.
Which I think is reasonable, given that I reject anything SA thinks is
spam, so this is only the false negatives.
