We recently undertook a major project to curtail the spiralling spam that was afflicting some of our clients servers. We applied several patches and upgrades and made some major configuration adjustments to secure our server along with better control of spam. After a month of tweaking and monitoring the mail servers we can verify that spam has been all but eliminated, of course spam is a plague with no certain cure but we are committed to ensuring continued service levels with minimum spam. The graph below shows the resulting mail queue for the duration of the project.
