Hi all, this is all "water under the bridge" now after a generally successful upgrade from 15.7 to 7611 but an issue has just been noticed nearly a week later by a customer whom noted that email forwarding stopped working on an account. Sure enough, the email forwarding box is now empty for the account in question. Previously, in 15.7, there were four addresses defined to receive forwarded messages. After looking through the system, nearly all accounts on all domains that had forwarding defined on accounts now have empty forwarding fields. I can't recreate the forwarding for them all without knowing what was previously defined by the customers. This is a minor headache which is why I'm reporting it.
