How to Disabe Outgoing SMTP for Some Users ?

Dear List Members,

I am using qmail-smtpd-auth 
(http://members.elysium.pl/brush/qmail-smtpd-auth/) with qmail and vpopmail.

If anyone knows a way out to disable Outgoing SMTP for certain users. (I am 
not using POP-before-SMTP).

Neither of these seems to do the trick:
disable_external_relay
disable_smtp

Thanks.
