We are a small ISP using Qmail for our mail server - we use a spam filtering device for our incoming mail but are having a real problem with our customers sending spam(deliberately or non-deliberately). Since we are not using public IP's we have a major problem with our IP address getting blacklisted and trying to track who's causing the problem. Does anyone know how we can filter outgoing mail for spam? We do have Spam Assassin installed on the mail server - can that filter outgoing mail?
Thanks
Dean
