Hi Richard, If you haven’t configured any email security on the backup MX then do you know if you are you seeing a larger amount of spam? Around 60% of the spam I am seeing is purposefully sent to the backup MX server which they then hope is forwarded on to the primary mailserver from a "clean" IP address. To be effective I feel that the backup MX servers needs to have exactly the same protection as the primary mailserver including knowing which users are valid and which to reject.
