I dont see a way to have AUTH&TLS to all of our relayhosts but not for this internal hosts.
sender_dependent_relayhost_maps = hash:/etc/postfix/relayhost_maps smtp_sender_dependent_authentication = yes smtp_sasl_password_maps = hash:/etc/postfix/smtp_auth smtp_sasl_auth_enable = yes smtp_tls_security_level = may smtp_sasl_security_options = noanonymous root@postgate01:/etc/postfix# more relayhost_maps @domain1.de [securerelay.tld]:25 @domain2.de [securerelay.tld]:25 root@postgate01:/etc/postfix# more transport domain1.de smtp:192.168.124.5:2525 domain2.de smtp:192.168.124.5:2525 So howto not use AUTH&TLS at all to 192.168.124.5:2525 ?
