That is for mail received via SMTP.
In your case use authorized_submit_users instead.

Thanks for replay.
The submit is done by httpd user, so this block all not mod-cgi sites. :-(
I had temporarely used a relayhost to other server where I can filter it
using the smtpd restrictions directives.
Any other hints appreciated ;-)
Thanks, B.
