Hello,
I have noticed that the mailspike rules are enabled in SpamAssasin but
all return zero values:
0.0 RCVD_IN_MSPIKE_BL Mailspike blacklisted
0.0 RCVD_IN_MSPIKE_L5 RBL: Very bad reputation (-5)
This is actually a rounding issue: all RCVD_IN_MSPIKE_* rules are being
scored at +/- 0.001 by RuleQA so the score report rounds it to 0.0. They
are rescored that way because they are not hitting anything in the
submitted corpora but have scores set in the static scores list.
That MAY indicate a bug in RuleQA, since I don't believe that "net"
rules like these should be rescored by RuleQA. Perhaps someone more
familiar with the mechanics of RuleQA will correct me...
I can't say about a RuleQA bug, but when these were first added I
investigated to see if they'd be worth a datafeed.
For our mail flow, they hit on a fair bit of mail.... but nearly all of
the messages were pretty strongly ham or spam without the MailSpike
hits, and they weren't hitting the intermediate mail, so I disabled them
all.
A quick crude eyeball through my personal domain's mail log (runs nearly
pure stock SA modulo minor Debianisms) shows plenty of hits, but the ham
is already strongly hammy (scores 0 to -10 or so) and the spam is
strongly spammy (only a light sprinkling at 9, and most of them close to
or over 20).
