Hello, i have this situation: Postfix server acts as relay for Lotus Domino (MDA) and everything works ok. Customer adds another Domino server because of HA. The second Domino server has different IP. Delivery process is obvious: when there is not available "primary" Domino server, send everything to the secondary one.
Please what is the best way to specify the secondary Domino server? The first one is specified in transport maps: domain.tld smtp:[IP_of_primary_MDA] another_domain.tld smtp:[IP_of_primary_MDA] ... Thank you for help, Jiri
