Hi guys and Matus

ok - smtpd rejection i have done before i thought but how i disallow the
bounce for the unknown ?

i meant that this lines in the main.cf where enough:

maps_rbl_domains = list.dsbl.org,
                   relays.ordb.org,
                   sbl.spamhaus.org

smtpd_delay_reject = yes

smtpd_helo_required = yes

smtpd_helo_restrictions =
         permit_mynetworks,
         check_helo_access hash:/etc/postfix/helo_access,
         reject_invalid_hostname,
         permit

smtpd_sender_restrictions =
         reject_unknown_sender_domain,
         reject_non_fqdn_sender,
         reject_unauth_pipelining,

smtpd_recipient_restrictions =
        permit_mynetworks,
        reject_maps_rbl,
        reject_unknown_recipient_domain,
        reject_non_fqdn_recipient,
        reject_unauth_pipelining,
        check_relay_domains

smtpd_client_restrictions =
         permit_mynetworks,
         reject_maps_rbl,
         reject_unauth_pipelining


mynetwork is 127.0.0.0/8 193.171.38.0/24
so where i have done the mistake *hmmm
