Hi all, i'm setting postfix server as primary and mx backup as well and i'm not using relay_domains directive. this is my configuration:
DNS domain.com IN MX 10 primary.server.com domain.com IN MX 20 secondary.server.com POSTFIX transport_maps = mysql:/etc/postfix/mysql_transport.cf Into transport maps i set some domain to relay on itself (no backup mx - relay:[primary.server.com]) and other domain to relay to other mail server (backup mx - smtp:[secondary.server.com]). Is this configuration correct or I need to use relay_domains too into main.cf? Thanks
