One of my pop accounts that I pull down via fetchmail which isn't controlled
by me just changed there spam filtering software. In the process of this
change they went from bouncing a lot of suspected spam, to now just
quarantining it. Since I don't use there quarantine, obviously I'm ending up
with quite a bit more spam than I used to.
Dspam is having a lot of trouble classifying these new messages as spam. The
strange thing is that all this spam looks very similar to the spam it is
catching. I'm starting to wonder if I should wipe my databases and start
fresh, it's been about a month and it doesn't seem to be getting any better.
I'm getting roughly 200 pieces of spam a day now. My stats have dropped
considerably from about 90% accuracy to less than 70 as you will see. Do you
think that if I continue to train it will get better, or do to the size and
age of my database that this new spam will have trouble getting classified?
Any info I can provide let me know.
