SMTP restrikce v postfixu

[Martin Bubik]

zdravim,
rad bych se poptal lidi kteri provozuji postovni servery jake pouzivaji 
restrikce u postfixu.
Svuj postovni server jsem dal dohromady nedavno a nejsem si moc jisty 
jestli restrikce,
ktere pouzivam, nejsou prilis prisne a jestli neprichazim o regulerni 
emaily, pripadne jestli
byste seznam jeste o neco doplnili, spamu mi totiz chodi docela dost a 
rad bych ho odfiltroval
co nejvic nez se to dostane do spamassasinu.
procetl jsem na netu spoustu doporuceni tak jsme to tak nejak 
sesumiroval a poskladal jsem tohle:

smtpd_helo_restrictions =
        permit_mynetworks
        permit_sasl_authenticated
        reject_sender_login_mismatch
        reject_invalid_hostname
        reject_non_fqdn_helo_hostname
        reject_unauth_pipelining
smtpd_sender_restrictions =
        permit_mynetworks
        permit_sasl_authenticated
        reject_sender_login_mismatch
        reject_unknown_sender_domain
        reject_non_fqdn_sender
        reject_unauth_pipelining
smtpd_recipient_restrictions =
        permit_mynetworks
        permit_sasl_authenticated
        reject_unauth_pipelining
        reject_sender_login_mismatch
        reject_unauth_destination
        reject_non_fqdn_recipient
        reject_unknown_recipient_domain
