I have a postfix mail gateway sitting in front of my internal Exchange 2013 mail servers. Currently have my "/etc/postfix/transport" file set to send mail to only one of those Exchange servers:
"domain.com smtp:192.168.1.108" Would like to setup multiple internal Exchange Server entries for failover purposes. I was thinking of doing something like this: "domain.com smtp:sub1-mx.hosts" But I forget how and where to setup the "sub1-mx.hosts" file. Any help would be appreciated...Ed
