In the race to provide the best anti-spam system to fight the ever-growing threat of spam email, there are a few which stand out among the for-pay software systems. Some are software programs, while others are web-based systems that function by sending your email through their service before it gets to you. The web-based filter has the added benefit of not permitting spam to get through to your system, in the first place; on the other hand, if valid email is filtered out and isn’t spam, its difficult to recover it.
Here are reviews of top-rated spam filters
Mailwasher:
The Mailwasher spam filter is a very efficient and secure spam filtering tool. It combines a number of different techniques to detect and delete spam before it gets to your inbox, as well as protecting your computer from viruses. These techniques include: using statistics, blacklisting and white-listing, databases and advanced learning filtration.
Mail Washer supports IMAP and POP accounts, as well as MSN, AOL and Hotmail. However, it does not offer IMAP or POP proxy filtering.
This spam filter takes a bit of time to “learn” what you think is spam, and in time will be highly efficient in its spam filtration.
