    Hi All.
    I have a few instances where servers attempting to send email to me report a bad fqdn during the helo process.
    554 5.7.1 <server.urichoffice.local>: Helo command rejected: Host not found; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<server.urichoffice.local>

    My Main.cf contains:

    smtpd_helo_required = yes
    smtpd_helo_restrictions = permit_mynetworks, reject_non_fqdn_hostname,reject_invalid_hostname,permit
    smtpd_sender_restrictions = check_sender_access regexp:/etc/postfix/tag_as_originating.re , permit_mynetworks, permit_sasl_authenticated, check_sender_access mysql:/etc/postfix/mysql-virtual_sender.cf, check_sender_access regexp:/etc/postfix/tag_as_foreign.re


    Trying to understand where I can put this "server.urichoffice.local" as a whitelisted thing
