    Dear couleagues,

    I would like to whitelist problematic mail hosts, but which are very important to us (they have alias domains, localhost domains, strange unlisted domains and so on).
    Previously i have used with success this tutorial: https://www.howtoforge.com/how-to-whitelist-hosts-ip-addresses-in-postfix
    based on which i should put this in /etc/postfix/main.cf: check_client_access hash:/etc/postfix/rbl_override

    This is the excerpt from the latest postfix in ISPC 3.2.1 (it is a lot different from the latest tutorial, so where should i put the rbl_overide now?):

    smtpd_recipient_restrictions = permit_mynetworks, reject_unknown_recipient_domain, reject_unlisted_recipient, check_recipient_access proxy
    :mysql:/etc/postfix/mysql-verify_recipients.cf, permit_sasl_authenticated, reject_non_fqdn_recipient, reject_unauth_destination, check_rec
    ipient_access proxy:mysql:/etc/postfix/mysql-virtual_recipient.cf, check_recipient_access mysql:/etc/postfix/mysql-virtual_policy_greylist
    .cf, check_policy_service unix:private/quota-status

    It is also very different to the acceptance of mail, a lot rejects before permit_sasl_authenticated which was always second.
    Should i change the order somehow or this is the new more secure way?

    Best regards

    Are you usign RSpamd or amavis?
    I have whitelisted in ISPConfig Panel, the Postfix Whitelist settings.

    Hi Taleman, thanks for your time.
    Do you mean that adding IP addresses or domains in Postfix Whitelist sender in ISPC panel is the same as making a manual rbl_overdrive file and postmap and then adding it in the main.cf ?
    Right now i'm using amavis, but next step is to test and then install RSpamd.

    That depends on which restriction you are adding an exception to. What is the error message you get when those are rejected?
