That's an interesting idea.  One would need to use a "from" instead
of "env_from" entry, because the envelope Mail_From value is "<>".
It would also be necessary to use the entire Mail_From value as in:

   ok    from    Mail Delivery Subsystem <MAILER-DAEMON@aol.com>

Another tactic might be to whitelist the Fuz2 checksum of the message.
It looks likely to be constant.
The Fuz3 checksum can be obtained with `dccproc -QC`.
