Hi!
Very anecdotal, but of the last 20 messages scored as spam, only 1 of them did not hit on any SURBL's. On a daily basis about 2 or 3 per user, out of an average of 200 to 300 non-spam messages delivered, were diagnosed as non-spam, and were not registered in the SURBL when delievered, but when manually checked later, their offending URL's had been registered in at least one, and often several, SURBL's. SURBL's are definitely workling.
We are working on even getting them added faster. Some parts of WS and some parts of JP are allready updating more often. Some pill spammers wont like this ;)
Its good that you look if its added allready, since only with THOSE submissions we can add more on the lists ... :)
Bye, Raymond
