Oh, bad Luck :-(
Indeed:)
Long ago I decided to 'trust the force' and delete anything which failed
the bayesian filter. That stops the backlog of messages for me but that
may not be acceptable for you.
Well I solved the issue by droping all address-error msgs.
But I'm still amazed by incredible ammount of msgs they can produce...:)
A while ago, like many people, I noticed those horrible scripts
attempting dictionary attacks on the SSH daemon. In the end I
implemented a fix I'd seen using iptables [1][2]. This involved
dropping any attempts to login using SSH if that same IP address had
previously failed to login for more than some threshold value. The ban
on the IP address was set to half an hour.
I wonder if something similar could be implemented here?
