Sorry, no idea.
There is always a delay between when the error is written in
dovecot.log and when I and ask the user what happened. The truncated
message is always one of the latest in the mbox, but I can't tell if
it happens when the message is the last one.

Maybe a debug message that logs the latest mbox uid together with the
"FETCH for mailbox Sent UID 7139 got too little data : 11112 vs 11160"
message could help.
Or maybe a debug extra check that reads every newly written mbox mail
if it's actually written up to the last byte...

Diego.
