spamassassin - block ip after several rejects
Hi,
I've got a postfix-mailserver in combination with spamassassin.
It checks, whether a local mailbox exists and if not rejects the smtp-request
immediately.
is it possible to block a senders ip-address let's say for an hour or a day or so,
if there was a certain amount of rejects?
so for example if a spammer tryies
a@..., b@..., c@..., d@...
the spammer's ip gets blocked for some hours and there will no smpt-session
opened at all from this ip any more during this blocking-period?
thanks,
toby
