After trialing several anti-spam procedures we have implemented SpamAssassin, one of the most reliable anti-spam systems available.
SpamAssassin uses a wide variety of local and network tests to identify spam signatures. This makes it harder for spammers to identify one aspect which they can craft their messages to work around.
All incoming email processed by our email servers passes through SpamAssassin.
To take advantage of our anti-spam procedures you will need to contact us so we can make the necessary changes to your email configuration.
SpamAssassin is an open-source software package from the Apache Software Foundation.
