Mailing list posting confirmation daemon

Project Description


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.


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.


Version 0.41.5 (20 Apr 2018)

  • Fixed dmarc_reverse() to not re-send to other addresses than the indicated recipient.

Version 0.41.4 (01 Mar 2018)

  • Fixed a bug in dmarc_rewrite(), where the return values from email.utils.getaddresses() was not handled properly.
  • Tweaked some setup error messages

Version 0.41.3 (21 Feb 2018)

  • Added warnings on failure for some post-install actions.
  • Changed the interface to accept multiple recipients when given on the command line (for use with dmarc-rewrite). Changed dmarc-rewrite to accept multiple recipients, and renamed the recipient argument for other functions that can accept recipient lists.
  • Changed the -e argument to log arguments to syslog and not exit.
  • Reverted an earlier change of socket ownership handling.
