maybe the problem results by the spam/mail filter/rules setup which is not intuitive (in my opinion).
There are two 'tag levels'.
I thought on first entering that page (and some time after...) that 'level 2' is just chance to get a different markup of already spam-marked mails. Some testing brought to me:
- Spam tag level is for setting X-Spam-Level and switching the subject ("tagged_above" in X-Spam-Status)
- Spam tag level 2 is for setting the X-Spam-Flag to YES ("required" in X-Spam-Status)
But there seems to be a problem(?) left when level 2 is left at '0' and level 1 is somewhat higher - in that case reaching the level 1 will set level 1 AND level 2 active, otherwise none of them get ruled.
So if You just set "Level 1" to a value (and leave the other unchanged - so they result to "0") every Spam Mail will be deleted...
So I decided to set Level 2 to the same value as Level 1 and set killed to 50... but that dependes to Your own bias.
