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~
