    Hi all,
    i'm trying to reduce the spam accepted by the server adding some options to in postfix configuration.
    I added
    smtpd_helo_restrictions = reject_non_fqdn_hostname, reject_invalid_hostname, permit_mynetworks
    and modified
    smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, reject_unauth_pipelining, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_unknown_sender_domain, check_recipient_access mysql:/etc/postfix/
    in /etc/postfix/
    tryng to reject all mails from not fqdn HELO senders, but with no results.

    in mail.log i can see a lot of warnings like
     warning: hostname does not resolve to address
    but no mails are rejects.

    Any clue ?
