napriklad:

smtpd_recipient_restrictions = reject_unknown_sender_domain, permit_mynetworks, reject_unauth_destination


reject_unknown_sender_domain
to by melo blokovat mail od odesilatele, ktery v "mail from:" ma spatne 
nastaveno/nenastaveno dns. 

permit_mynetworks
postfix doruci zpravu pro jakoukoliv destinaci, pokud adresa klienta,
kontaktujiciho smptd, je v rozsahu definovanem pomoci parametru "mynetworks"
to aby alespon nekdo mohl odesilat.

reject_unauth_destination
prijme pouze zpravy pro specificke domeny a prijemce nastavene pomoci "mydestinations",
"relay_domains", "virtual_alias_maps" atd. ostatni odmitne.

to je tak v kostce. pro presny popis a vychytavky viz:
