Hello, I've started to get spam this week, seems that, or this has been applied to 9grid.es
"Caution: If your usage should exceed the free use criteria your access to Spamhaus's public DNSBL servers is very likely to be cut off without warning." or they are missing some "well-known" sources of spam. I've registered 9grid.es in http://www.barracudacentral.org/rbl/ and they are already blocking the spam emails i've got. slds. gabi
