I still don't understand why the "Type" can't be added by itself.

Just a note before forwarding you to perldoc, the module source code and zwon for further study:

you correctly wrote in the opener: $message->replace(Type=>'multipart/mixed');, and this indeed **works** and changes the mail structure you set with the Type=>... assignment during ->new/->build.

Without an explicite Type, Dumper shows a non-MIME text/plain message. Adding mime parts seems to turn the original body (that you never defined in the opener or Re^4) into our undefined problem mime part, while also turning the Type to multipart/mixed. If my assumption is correct, just setting Data=>"" (and never setting a Type at all) before adding attachments should also avoid the undef bugs.
