Central Email changes
We just lost a customer because of a weird situation.
the two AWS IP's that Sophos sends through, one was stuck on the client's hosting provider's "poor reputation" list - which caused 1/3 to 1/2 of their email getting stuck in a "queued for delivery" loop. I beieve that the system should detect rejections as well as delays, and route mail through the other outgoing IP that Sophos has in AWS, it would have avoided this mess entirely.
Separately, it would be a huge benefit as well to allow multiple MX records, for redundancy on the client end as well.
