What is the Best Spam Filter System For Mac?

Macs deserve shiny handy welcome useful classy spam. You mean there's no such junk mail?

Let's go for no spam at all then: find the best junk mail filters, both free and commercial, for Mac OS X here.

1.  SpamSieve - Mac Spam Filter

SpamSieve lets you add superior Bayesian spam filtering to Mac OS X email clients, is just as easy to use as Mail's junk mail filters, and can give you statistics, too. 

2.  SpamSweep - Mac Spam Filter

SpamSweep successfully combines high precision spam filtering with a simple and easy to use interface. It's a pity processing mail is a tad slow in SpamSweep, and a POP proxy mode would be nice. 

3.  POPFile - Mac Spam Filter

POPFile is a powerful and flexible email classification POP and NNTP proxy that you can use to filter spam efficiently and categorize good mail automatically. Unfortunately, POPFile can grow a bit heavy on memory and CPU load if you have trained on lots of mail.

4.  Spamfence - Mac Spam Filter

Spamfence is an effortless but highly effective spam (and virus) filtering service.
Its only real shortcoming is that Spamfence relies on forwarding and requires two different email accounts.

5.  Spamfire - Mac Spam Filter

Spamfire combines efficient Bayesian filtering and ease of use to form a great anti-spam tool. It could integrate with email clients even better, though, and be a bit snappier overall.

6.  Spamato - Mac Spam Filter

Spamato filters POP and IMAP accounts for spam with the potential for high precision and plug-ins that make it easy to use in Outlook and Mozilla Thunderbird. Unfortunately, Spamato can be a bit overwhelming with its multitude of options and little help. 

7.  Personal Antispam X5 - Mac Spam Filter

Personal Antispam X5 employs a number of tactics to rid Mac OS X Mail and Entourage of spam — a bit overeagerly unfortunately.

8.  SpamBayes - Mac Spam Filter

SpamBayes employs sophisticated analysis using Bayesian statistics to rid your email Inbox of junk mail precisely and in an effortless manner.
It would be great if SpamBayes' classifying power could be used to further categorize and prioritize good messages, and plug-ins for programs other than Outlook and Mozilla Thunderbird would be welcome.
