In the last couple of weeks, I've suddenly started having tons of spam get by SA. Up until then, things had been working beautifully for a number of years (with occasional upgrades and tweaks, of course). I'm not sure what has changed, but something seems broken. I upgraded to 3.1.2, but it didn't seem to improve things much. I also am not seeing an obvious pattern to the things that are getting through. Some of them are actually getting autolearned as ham, which is probably making the problem even worse.
Here are several example messages that have gotten through in the last day or so (including the scores they got): http://dogcow.org/tmp/spam-misses-20060602/ I have SA installed locally in my home dir, running through procmail (no spamd/spamc involvement). I theoretically have network checks on (I'm not running SA with '-L'). Any thoughts on what is going wrong here? Thanks. Sean
