postfix rewrites address to non-verifiable form

web1.bcenclave.ca hosts a virtualmin pro domain - wheeldoc.ca. A html web-to-email form collects user input and is set to use cgiemail to send mail. The form completes successfully but the email sending fails like this:

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.
 
For further assistance, please send mail to postmaster.
 
If you do so, please include this problem report. You can
delete your own text from the attached returned message.

And I don't know where else to look. Suggestions?

Try adding the line mydomain = bcenclave.ca to main.cf and then restarting Postfix.

Alternately, whatever script sends email needs to set a valid From: address.

good suggestions, no fix yet. I saw in the process that rdns is not set up so am waiting for the ISP to fix that, will let you know.
