Right... but I don't want to get rid of SURBL... it is working very
nicely, it finds a lot of spam and I have yet to find a FP myself
(though others have seen them)...
My question is more to the people that developed the SURBL plugins for
SA (or those that have read and understood them), to know if there's
something in the plugins to avoid a DoS attempt of this kind.
Thanx for your reply, anyway.
