Can you define multiple "server.mail.host=xxx.xxx.xxx" in the hq-server.conf to ensure alerts are forwarded?
Let's assume you have relay1 as your primary SMTP server and relay2 as a warm standby in a non-HA configuration. The Hyperic server is set to use server.mail.host=relay1. If for some reason the SMTP daemon goes down on relay1 I will no longer receive alerts (including the one notifying me that SMTP went down). The need for email server clustering/redundancy/HA aside, can I specifiy multiple SMTP hosts and have Hyperic itself fail over to a secondary if it can't connect to the first?
