SpamSieve Now at 95% effective vs. near 100%

Lately, SpamSieve, which was almost at 100% effectiveness, is allowing a few spam emails into my INBOX; just a few here and there. Small, but noticeable.

FYI, my Corpus is getting pretty big which I hear “isn’t necessarily” a problem, but I wonder.

Any help?

Thanks.

I’m on an 2.8GHz Intel iMac running Mac OS 10.5.6 and Spamsieve 2.74

There could be any number of causes of that behavior. Please see this page.
