Also if it helps, I do have the Spam filter enabled as well.

receive_override_options = no_address_mappings
Personally, I put this in the master.cf file. As an addition to the existing no_header_body_checks so (probably last line in file) looks like...
127.0.0.1:10025 inet n - y - - smtpd
<other stuff here>
DOn't know which location would be preferred though.

Thank you very much. Strange that the posts I had been looking at did not have the underscores in the parameter. I added:
receive_override_options = no_address_mappings underneath the content filter line in my main.cf, did a sudo postfix reload, and all is well. No more duplicates.
I have yet to tinker around in master.cf, though I see that there are interesting filtering settings there.
