* messages with the same ID, but that should be good
* enough. A more general implementation would have to store
* ever-growing lists of seen message-IDs; in a long-running
* daemon this would turn into a memory leak even if the
* implementation were perfect.

* to break it in a way that blackholed mail. Better to pass
