The RFC says you CAN try other MS records, not that your mail server MUST try them. Some mail servers do and some don't. Your reference supports this: "In addition to specifying the mail server which should receive mail for a domain, MX records can also specify the host(s) to which mail can be delivered if the primary mail server is off-line." CAN be delivered is different from MUST be delivered. That means that some email might be delivered to the secondary MX. > I would definitely set up the system with 2 drives in a raid 1 > configuration.
