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!
