Look at the raw stored messages. Your MTA probably has an internal ID (queuid in
postfix) that should tell you if the messages are getting duped before they get
to dovecot.

the raw messages should have time stamps showing when they were written, so that
will give you something else to check in the logs.

Both you mail and dovecot logs, of course.

Since these are local emails on one server, is it possible that server is
sending mail to the other server that is coming back as a second copy?
