You could add a rule to /etc/procmailrc (or ~fax/.procmailrc) to parse
and forward it.  Assuming the fax account's username is "fax" and that
"fax" is aliased to you, how about something like this in your
$HOME/.procmailrc:

	:0
	* ^To:.fax			# Was it sent to "fax" AND
	* ^Submitted by:.*		# Does it contain "Submitted"?
	{
	    :0 fhw			# Yes, parse rest
	    * ^Submitted by: \/[^ ]*	# Pick up who sent the job
	    ! $MATCH			# Forward the mail to them.
	}

That should pick up any mail addressed to the user "fax" that also
includes "Submitted by:"  and forward it to whatever user is specified
in the "Submitted by:" line.

I won't vouch that this exact script works, but the concept is sound.
See "man procmailrc" and "man procmailex" for details on recipes.
