Ever notice when you're doing something to help kill spam you don't get any? Ugh.
I've just deployed the 3 surbls on one of my server for testing and of course it is the one I get my personal mail on. Usually overnight all I get, for the most part, is spam.

Heh heh heh.
I had exactly the same problem... My spam folder usually gets about 100 a day, and for nearly 3 hours after I implemented surbl I didn't get a single spam :( Seems like my spam comes in big infrequent bursts during the day, with most of it at night...
Fortunately I have a couple of workmates who get several times more spam than me and kindly let me browse their spam folders ;-)
