Hi all, Pervious, I have installed POSTFix + SpamAssassin. They are doing the job very well. They can stop the spammer sending Virus and spam. But there is still a leak in email server. If one of our user got the email contains virus from a person he/she knows, not spammer, SpamAssassin may not stop this. So I have installed Clam AV. Does any one try to config it with POSTFIX + SpamAssanin? Would it be very slow? The message has to pass spamd and clamd. Regards, Michael
