Hallo Vietse, thank You very much for Your support and Postfix!
I have one more question, maybe here You will be also able to help. You said that "Postfix will not look in DNS...". Our E-mail environment base on Postfix and Exchange and we are using local domains to balance E-mail traffic between nodes. If DNS look up is only intentional, then how to properly configured SMTP relay ? In my environment E-mail is going thru several network zones to different departments and in most cases everything is configured using /etc/postfix/transport table. domain.com relay:mydomain.local Internal domain with MX records is kind of loadbalancer (with high availability) in that case. So how to properly route E-mails to different domains where each department has 2-3 mail servers. In the configuration files, should I specified "IPs" with comas etc.etc. ? Thank You in advance for any hint.
