Question
I have GMS set up to send all mail entering my server destined for non local domains on to another server. For security I would also like to be able to specify a secondary server. How can I do this?
Answer
When setting up your rules you can specify multiple servers under the "Post Server" section of the rule. These multiple servers must be separated by a comma.
An example of such a would be:
Target Address: * Deliver to: mail.dom1.com, mail.dom2.com Port Number: 25 Retry every minutes: 12 Account: (blank) Password: (blank)
