Description Bob Menschel 2003-11-12 21:05:30 UTC 
Per attached email, the United Airlines Mileage Plus loyalty program is now 
using an email address of: 
United News <MileagePlus@UnitedOffers.com>
This matches the FROM_OTHERS rule, which: 
score FROM_OFFERS 4.300 3.932 4.095 4.100
and too easily leads to false positives.

Comment 4 Daniel Quinlan 2004-10-26 18:02:18 UTC 
The score is now lower... do we still want to change this rule?

score FROM_OFFERS 1.822 0.861 2.243 1.491
Comment 5 Justin Mason 2004-10-26 18:29:16 UTC 
we could even drop it at this stage.

  0.105   0.1571   0.0035    0.978   0.56    1.82  FROM_OFFERS
Comment 6 Bob Menschel 2004-10-26 21:38:25 UTC 
It remains a good spam rule here. With the lower score in 3.0.x, I think we're 
OK.  I'm on the road and so cannot do a full mass-check at this time, but a 
quick egrep of my corpus indicates the rule is contributing significantly to 
SA's efficiency.  (Happened to receive a spam today, total score 9.4 on my 9.0 
required, that would have been FN except for this rule. Spamcop and SURBL rules 
did most of the work, but FROM_OFFERS pushed it over the edge.)

FROM_OFFERS no longer matches, closing
