I'm planning to enable bounce verification on my C300 (AsyncOS 5.1.2) and I'm trying to figure out how to keep everything running.
My problem is that the advanced user guide states that "AsyncOS consider bounces as mail with a null Mail From Address [...]" and I found out that receipt notifications are sent with a null mail from address and the same happens for out-of-office messages, so I think I would lose those messages.
Setting sender groups is not an option to preserve them, since they can originate from any mail server.
Has anyone had these kind of issues with bounce verification ? is there any workaround ?
