Latest version

greyfix-0.3.5.tar.gz (PGP signature)

  • Backward compatibility fix for Berkeley DB 4.2 and before.
  • Add --help and --version options, thanks to Stefan Siegel.

Features

  • Low and tunable resource usage and high efficiency. The program is written in C and uses Berkeley DB to track mailers. By itself it allocates memory only for a single request and the Berkeley DB library can be configured to use very few RAM.
  • Integrates with Postfix's master daemon. Postfix will shutdown greyfix when it is not used completely freeing its runtime resources.
  • No administrative burden. Everything happens "automagically".
  • No need for a database server. Uses Berkeley DB which is already installed with most free Unix distributions.

Requirements

  • Postfix. Greyfix is designed exclusively for it. It will *not* work with other mailers.
  • Berkeley DB 4.1 or later. Chances are you already have it.
