I took a look in my change logs to see what changes I made and why.
I have seen both of these cases more of the first mentioned than the
second.
I will monitor to see if any of these surface again.
The first is an easy fix but not so much of the second.
thanks

Duplicate messages in mailbox can result from:

or mail app) can time out before qmail-smtp acknowledges receipt. This
happens most commonly with large emails submitted from Outlook that
has insufficient timeout (should be max value).
These are the conditions that come to mind for me regarding duplicates.
HTH.
