I can advise you to use mail/spamass-milter for you mail server. If your clients gain there mail though pop3 then you can use mail/p5-Mail-SpamAssassin as a (getmail) filter. It realy realy good. I only had one false positive once. You can reject spammails if you like. Don't send bounce messages since these will not end up with the spammers but those who abuse the email adress. -- Alex Please copy the original recipients, otherwise I may not read your reply.
