BarracudaCentral.org Reliably Blocks Rash of New Spam

I'm using several DNSBL's to block inbound spam, plus blocking China entirely, which makes for a very quiet inbox most of the time.

Suddenly there has been a rash of new spam that the old BLs just didn't catch and it started to escalate.

Initially I wasn't too concerned because a spam site pops up, you get a few emails, they get black listed and the DNSBL blocks them from then on.

This time nobody seemed to be stopping them, none of my go-to DNSBL's were working so I revisited the DNSBL Spam Database Lookup site and started testing the source IPs of the email to see which list would block them.

Much to my surprise only 2 lists, barracudacentral.org and spamcannibal.org were highlighting these spammers at all.

After extensive testing BarracudaCentral.org proved to be the best out of the two so Barracuda gets added to my email filter list.

If you haven't tried BarracudaCentral.org then you probably have spam ;)

UPDATE: a few spams slipped thru that only SpamCannibal flagged so since I'm in a zero tolerance mode, I added SpamCannibal to my filter list as well.
