Use a policy service, such as postfwd, to set up rate limit and daily limit for each account/each server. Use amavisd-new/spamassassin/clamav/clamav-Sanesecurity addon signatures to scan outbound mail. Create a system to alert you when something is detected. We've had a handful of accounts get hacked over the years and (so far anyway) have been able to catch them before getting blacklisted. -- Noel Jones
