Dear All

Our organisation currently utilises both an exchange and linux mail server for different companies.

The linux mail server is more stable and is located in a datacenter whilst the exchange server is located at our headoffice. The linux mail server is configured with spamassassin, we wish to have this server as a backup mail exchanger for the domains pointing to the exchange server and also filtered from spam with spamassassin.

I managed to set up the linux mail server to be a backup mail exchanger via cpanel and everything works fine, however mail is not being filtered by spam assassin.

Any ideas ?

Thanks for your help
Justin
