POPFile
POPFile is an email classification tool that can be used to spot and isolate spam automatically.
Using Bayesian filtering, POPFile will "learn" what you teach it concerning sorting and storing fascinating versus spam.
POPFile can be used as an SMTP proxy before you mail server to filter all of your mail. This means you can use it with almost any email client. If you employ an NNTP news reader, POPFile can classify news things as well.
POPFile uses a net interface for configuration and correction of choices regarding spam.
Pros
* Works via net interface
* Will be used as a POP proxy as NNTP
* Uses Bayesian filtering
Cons
* Can be a memory and CPU hog
* Not optimized for enterprise use
SpamExperts
Initial the great news: SpamExperts requires virtually no configuration out of the box.
Currently the bad news: the occasional re-configuration typically needs a reboot.
Beyond that, SpamExperts is pretty easy to use. It uses a mixture of checksum analysis and a Bayesian filter. Not certain why it runs thus slowly sometimes. I do apprehend that obtaining your mail is going to be a 2-step process: initial SpamExperts has to travel get and then examine your mail. It will be configured to do this within the background. Then, you've got to truly retrieve the good mail that is left.
SpamExperts can additionally quarantine any email it's unsure about. That means you'll be able to go in and search, coaching the Bayesian filter to acknowledge it the subsequent time.
Professionals
* Works without any configuration
* Supports POP and IMAP accounts
Cons
* Slow to method and filter incoming mail
* Re-classifying mail is not the simplest issue to try and do
* Cannot kind by spam score
* Changing some settings requires a reboot
Spamihilator
Spamihilator works as a proxy for POP and IMAP mail systems. This means that it can work with just concerning any email software and isolate spam before you download it.
It uses two techniques for catching spam: A Bayesian filter and one thing known as Distributed Checksum Clearinghouse (DCC):
The basic logic in DCC is that almost all spam mails have many copies floating around. Any server using DCC that finds a spam email creates a checksum (adding up the basic components of the message and then creating a shorthand price). The server then posts this value to a central database. The next server receiving this email would get the DCC results and can a lot of simply establish the e-mail as spam.
The one thing Spamihilator doesn't do is mark spam for additional filtering via your email client. Additional than two categories of mail for automatic classification would be nice, too.
Execs
* Spamihilator will be used with any email client as a result of it works as POP or IMAP proxy.
* Combines multiple techniques for filtering spam which makes it terribly effective.
Cons
* No remote web-based mostly administration
* Will not classify and/or categorize your good email
SpamPal
SpamPal uses an "a la carte" approach for eliminating spam. This means that you can combine and match varied totally different techniques:
* Blacklists
With SpamPal put in you'll select from a variety of printed lists of known spammer domains and servers. If you receive mail from one of those sources, it can be identified as spam and isolated.
* Whitelists (manual and automatic)
This can be a list of contacts that you choose are acceptable to receive email from and should not be sent to the trash folder. SpamPal can facilitate your build such a list automatically (faster) or manually (a lot of accurate).
* Bayesian filtering
* Content scoring
SpamPal works with any email program as a result of it acts as a proxy.
Professionals
* Uses Bayesian filtering also many blacklists
* Works as a POP and IMAP proxy thus you'll be able to use it with nearly any email client
* Includes SpamAssassin (a server-side anti spam program that uses content-matching rules, plus DNS-based mostly, checksum-primarily based and statistical filtering)
Cons
* SpamPal isn't fully proof against blacklist problems
* DNS blacklists are slow-performing and suck up a lot of bandwidth
