I have similar problem (using linux host with some UUCP downlinks).
UUCP site runs sendmail 8.8.8 , linux runs zmailer 2.99.43.
I am able to fake From: addres (at UUCP site in sendmail 8.8.8):

From: Jan Novak <jnovak@dbp.saske.sk>
To: Peter Druhy <pdruhy@kosice.upjs.sk>

(dbp.saske.sk is UUCP connected site), but zmailer delivery
is refused by receiving mailer with the following:

<smtp kosice.upjs.sk pdruhy@kosice.upjs.sk 65534>: ...\
        <<- MAIL From:<dbp.saske.sk!jnovak@dbp.uucp> BODY=8BITMIME SIZE=1480
        ->> 501 <dbp.saske.sk!jnovak@dbp.uucp>... Sender domain must exist
(this is abnormal, investigate!)

Could somebody advise me how to make zmailer (or rmail from which I believe
zmailer has this UUCP-shaped MAIL From:) to produce:
MAIL From: jnovak@dbp.saske.sk

???
