Postfix is delivering the mail to dovecot.  This is done via the deliver
program or lmtp which are pipes, not files.  Thus, why is Postfix
attempting to write files in the user's mail directory?

You write new mail to the mailbox file with either Dovecot or Postfix,
not both.  Fix that problem and the locking problem disappears.
