NoSpamProxy … and the hassle of spam is over …
NoSpamProxy is a spam protection system that does more than just sort
your E-mail. NoSpamProxy already scans E-mail during SMTP receipt and
classifies the E-mail in accordance with various filters. If an E-mail is
classified as spam it is not accepted by the system. If the E-mail is
classified as trustworthy it will be let through.
NoSpamProxy is an intelligent system that learns from incoming and outgoing
E-mails.
Outgoing E-mails are scanned by NoSpamProxy and memorised as being
trustworthy. The software assigns trust points (bonus points) in the case of
outgoing mail to the recipient of the mail. This database is then queried in
the case of incoming E-mails and if there is an existing business
relationship (trust points), the E-mail is let through, even where other
filters would classify it as being non-trustworthy (e.g. the sender is
blacklisted, nature of content etc.). Should, however, a trustworthy E-mail
not be accepted because it has no trust points and the other filters do not
categorise the E-mail as trustworthy, the sender of the E-mail is informed
of the delayed delivery by his mail server!
