Still a bad idea, any other email that comes in during that time will may
become collateral damage to the unreasonably short queue lifetime. To
expire mail to an unreachable destination that tempfails, add a transport
entry:
somewhere.example error:5.1.2 destination unreachable
rebuild the transport table, send one message that's not to that
destination (to flush the IIRC queue-manager's one-slot transport
resolution cache) and then flush the queue. Avoid changing the
queue lifetime.
