If only two mailboxes, can one presume also a limited number of
correspondents / servers in total?
If so, you may be able to solve the problem at the source.
Suspicion is that one end or the other is running out of time due to
large file size and other delays.
See if setting log_selector= +all turns up evidence.
You MAY then be able to get the specific subset of servers involved
adjusted to longer smtp timeouts.
Yo umight also want to try use of 'unseen' instead of shadow tranports,
at least for debugging. These don't break all at once, so even if
delivery is not perfect, you may have more visibility.
