Mark Mayo of VMUNIX discusses his move to SpamSieve. I think he will be pleasantly surprised at how well it handle a butt-load of junk mail. Sure, sometimes with large loads of mail, it takes a minute to get processed through SpamSieve, but it does a great job at learning what is junk and what isn’t. I get on average 100-300 spam emails a day, and SpamSieve keeps on chugging. It works great in combination with SpamAssassin and other spam filtering utilities that tag spam in the headers since SpamSieve can learn about the spaminess of any portion of an email, including all headers. A++.
