I am certain it is the EXACT same message.
How do I know this?
The message ID's for the duplicate emails are exactly the same:

Message-ID: <mailman.2147.1169820047.30843.list at mailserver.domain.com>

Could this be a postfix issue? I don't think so ... because my other,
regular messages, are being sent without duplicates.
