Review comment:
       I think we might have to suspend the default action, otherwise after resuming the mailbox processor would not blocked  on waiting for the next mail in `processMailsWhenDefaultActionUnavailable`, instead it would repeat the loop of check mail exists & run default action, which would be similar to a `while` loop~
