    I'm trying to setup my server (mx2.domain.tld) as secondary mail server. It should relay all emails from known domains to proper servers - in most cases mx1.domain.tld - server in LAN, but without ISPConfig installation).

    On mx2.domain.tld I listed all known domains in postfix main.cf file:
    relay_domains = domain1, domain2, domain3, ... , domain20
    relay_recipient_maps =
    mydestination = server2.domain.tld, localhost.domain.tld, localhost
    relayhost =
    smtpd_delay_reject = no
    smtpd_helo_required = yes
    smtpd_helo_restrictions = reject_invalid_hostname, reject_unknown_hostname, reject_non_fqdn_hostname
    smtpd_client_restrictions = reject_unknown_client
    smtpd_sender_restrictions = reject_unknown_sender_domain, reject_unverified_sender
    Unfortunately I'm still getting such error message:
    I also tried to use ISPConfig feature: Emails -> Global filters -> Relay recipients but it didn't work.
