I'd like configure a backup mail server for my domain. The backup mail server is a RedHat box in another domain. It would seem I need to do the following:
1) Create a higher numbered MX record in my domain's dns entry that points to the backup mail server. 2) On the backup up mail server, configure sendmail.mc to uncomment the line containing "FEATURE(`relay_based_on_MX')dnl". Is this all that is necessary? Will this configure the backup mail server to store all email for my domain if my domain is unreachable and forward it when it becomes reachable? Or does this just allow it to relay but some other configuration is required to allow for store and forward. How can I test that this actually works? If I shut down sendmail on my primary mail server, how can I verify that mail actually was stored and forwarded via the backup once sendmail is restarted on the primary?
