Hi, I just would like to know if its possible to configure muliple IP`s of SMTP servers in this configuration file:
check_sender_access regexp:/etc/postfix/check_sender_regexp At the moment we are forwarding message with following sender E-mail address to one of our MS Exchange servers. /zelezny.niezale...@domain.com/ FILTER smtp:[192.168.2.100] How may I setup in this file some kind of "backup MX" server if smtp:[192.168.2.100] will be down. Is it possible to setup for example 3x IP`s ? If yes, how to do it ? Single IP address of smtp relay in our high available environment is not allowed. I cannot use local domain with MX records because dns lookup has been disabled. Maybe somebody will be able to support me here ? Thanks in advance for any hints ! With kind regards Zalezny
