If a certain site hits my mail server more than X times, based on
where it is coming from in the world, it is blocked in the sendmail
access.db for an hour. It works well for me.
MailScanner also gives you industrial-strength anti-virus and anti-spam capabilities, by being able to use up to 14 different anti-virus engines, SpamAssassin, DCC, Razor, and other anti-spam/anti-phishing features. It is the best thing for email since sliced bread.

Hello, I've got an ipfilter firewall also providing nat services. It forwards email to a natted smtp server. This email server is repeatedly getting hit by IP's atempting to spam it. I was wondering if it's possible either on the gateway machine or the email server, both are running ipfilter to drop an IP say for example 192.168.111.222 if it hits, is dropped, reconnects, and so forth, x times within say a given minute? Thanks. Dave.
