Status: RESOLVED INVALID

(MailNews Core :: Filters, defect)

Description

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.3) Gecko/20100505 Gentoo Firefox/3.6.3

All mails from the ACM, with the notable exception of the technews list, are marked as junk. Always. No matter how often (and I've been at it for about a year and a half now) I hit the 'not junk' button, it keeps getting junked by the filter. This accounts for about 90% of all mail marked as junk, in other words, the false positive rate is about 90%, and all of those false positives are sent from the same domain. 

Reproducible: Always

Steps to Reproduce:
1. Acitivate adaptive junk mail filter
2. receive mail from ACM
3. watch all said mail being junked
4. mark as not junk
5. repeat 2-4 ad nauseam
Actual Results:  
ACM mail still marked as junk

Expected Results:  
ACM mail no longer marked as junk

Same problm exists on Windows variants. Same problem has existed literally for years in earlier versions.

The most common cause of this is that you are only training junk, and not good. The adaptive filter requires about equal numbers of each. You can train as good by selecting some known good messages, and pressing shift-J

The JunQuilla addon will show you how many of both good and junk you have trained, as well as a host of other information about the junk processing.

rob, please comment if you are still seeing a problem. For now, assuming comment 1 is accurate.
