Mail2Web is a gateway between email and Web service for places where no direct Internet connection is available, but email can be used.

MailChariot's only mission is to get your incoming email (for example from /var/spool/mail), filter it through a spam filter, and put it into a spam or ham mailbox. If you don't agree with the spam filter's decision, you can move it to the notspam or notham mailbox and MailChariot will mark the message as ham or spam respectively. This design is mail client agnostic. It is ideal for use on shared hosts where the provided spam filtering is not effective enough.
