As soon as the error occurs, The Postgrey daemon would stop running, Postfix was then unable to communicate with it and no more mail would be delivered correctly, OUCH! Anyway the good news is the problem was discovered to be an incompatiability between Postgray and one of the OS libraries - libdb . My immediate solution was to setup a cron job that checked to see if Postgray was still running, if not - it would fire it up again, Not great but effective I know. Thankfully now an updated version of libdb is available and you can get it by adding the following apt source to sources.list; <code>deb http://us.archive.ubuntu.com/ubuntu gutsy-proposed main</code> and then updating libdb with the following apt call; <code>apt-get update && apt-get install libdb4.4</code> FAO UBUNTU 7.10 (GUTSY GIBBON) Users.
