mvmf: mvmda -- Mail Delivery Agent

Capsule Summary   Detailed Info
     

mvmda is a Local Delivery Agent for email, aka a Mail Delivery Agent (MDA).

mvmda can also be used as one of a chain of mail processing programs.

mvmda makes use of the MFL scripting language, which you can use in powerful ways to control the delivery of your incoming mail.

Since MFL has a well-defined syntax, its scripts can readily be produced by a front-end code generator (e.g., a web-based front-end).

mvmda knows about the MIME structure of the message that it handles.

mvmda is not a product, it is a program written primarily in C++, and you may freely download it and use it.

Overview

mvmda is a mail delivery and processing engine. It provides for intelligent handling of mail delivery, either as a final mail delivery agent (MDA) aka local delivery agent (LDA), or at another point in the delivery chain -- incorporating features for spam filtering, other filtering, and making decisions about how incoming mail is treated.

mvmda is controlled by the mfl scripting language, which combines an implementation of the SIEVE filter language and a C-like language in a powerful way. Using this language (or an interface that emits this language), users can direct the delivery and filtering of their incoming email.

mfl's language duality makes it very easy for beginning or novice users to write scripts (primarily or even exclusively using SIEVE elements) and yet provides advanced features for people of a more technical bent. On the other hand, the language can easily be generated by a user-friendly front end.
