Mailing list posting confirmation daemon

Project description

Caution

This is an alpha release. While the functionality is sound, the packaging is probably not even beta quality. Compilation of the components written in C has only been tested under Linux.

Description

postconfirm consists of postconfirmd, which is the long-running (daemon) part, and postconfirmc, which is the client part of a client-server program which handles email confirmations. It is intended as a front-end to mailing lists. It provides funcitonality which is a subset of TMDA, but is adapted to high-volume usage and does not have anywhere near all the bells and whistles which TMDA has. On the other hand, since the whitelist lookup is done by the long-running server part, the overhead of doing a verification that a poster has a confirmed address is much smaller than for TMDA. This makes it a factor 1000 or more faster than TMDA in production, with a memory footprint a factor 20 smaller.

Changelog
