It seems many of the major commercial players (Brightmail, Sophos) charge per-user rates that make it difficult to the bottom line. One of the goals is to prevent the mail from actually hitting our = backend Qmail systems, but at the same time give users the ability to weed = through their messages in a quarantine. Initially we wanted to deploy Spam = Assassin but haven't found any quarantine method available. So - my question is what some of you were using for ISP-based antispam, = and do you know of a user-manageable quarantine for SA? We have roughly 90k users and 11k domains. Thanks for any input or critiques you may have... -- Phillip Salzman http://www.sysctl.net/phill/
