Hi!
And exactly why dont you block those on your MTA? Bit waste on CPU cycles like this... first process then, and then trash it anyway.
Well, mostly because I don't have any idea how to do so at the MTA level and also I would think it would be harder to add other offending IPs in the future.
Not at all ... You can even drop the IP with a route command. Do: route add -host <ip> reject Easy as that. Bye, Raymond.
