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.
This is a form of MDA and just means delayed MDA process completion but
message is not going anywhere from there. Month quees for pickup are
pretty rare nowdays anyway.
