login without authorization - Postfix/SASL
login without authorization - Postfix/SASL
I have a problem with logging without authentication on the port SMTPS (465) postfix, because
because security is not working
In configuration I have:
smtps     inet  n       -      n       -       1       postscreen
 -o smtpd_tls_wrappermode=yes
 -o smtpd_sasl_auth_enable=yes
 -o content_filter=smtps
 -o smtpd_client_restrictions=permit_sasl_authenticated,reject
 -o smtpd_sender_restrictions=reject_unknown_sender_domain,permit_sasl_authenticated
 -o smtpd_recipient_restrictions=permit_sasl_authenticated
 -o smtpd_relay_restrictions=permit_sasl_authenticated,reject

On port 25 and 587 is OK, ie. not logged without authorization, in my configurations have:

smtp      inet  n       -       -       -       -       smtpd
 -o smtpd_client_restrictions=permit_sasl_authenticated,reject_unauth_destination
 -o smtpd_sender_restrictions=reject_unknown_sender_domain,permit_sasl_authenticated,reject
 -o smtpd_sasl_auth_enable=yes
 -o smtpd_recipient_restrictions=permit_sasl_authenticated
 -o smtpd_tls_security_level=encrypt

Does anyone know how to just block port 465?
any ideas?
