we use 3 different smtp gateways (hosts) to receive email from the internet, each of these gateways has its own mx record if mx1 is not accessible then all is routed to mx2 and eventually mx3 if mx2 is not reachable. All of these gateways the forward email to one of our domino smtp servers, we also use this gateways to send outgoing email to the Internet. I have gateway 1 FQDN as relay in domino smtp configuration specified and this is all working ok, but I’d like to use mx2 and mx3 gateway as backup (failover) in case gateway mx1 is down so email messages eaving out local domain are routed out either by mx2 or mx3… can this be done?I tried to put FQDNs for mx2 and mx3 in 2nd as 2nd and 3rd line as relay in smtp config doc but it does not sounds like domino knows about it or can do it, because if I purposly shut down mx1 outgoing email is stuck in mail.box file… incoming of course still coming in via mx2 and mx3
any ideas?
