The maximum time that mail stays undelivered on peoples queues before
being bounced. Theoretically unbounced but in practice a week or so.

Some large ISPs who deliver email to their users over SMTP keep messages
on their queues for up to a month, to allow for users who dial up
infrequently.

The recipient SHOULD NOT reject messages in that situation anyway,
because they'd be generating a bounce to an address which they _know_
wasn't responsible for the mail.
