Configuring QMail as a fallback server 1

[edelapatte]

Am a newbie. In the DNS for our domain we have a primary mailserver and a second server to receive the mails when the primary is not working. All I want is the second-one to act as fallback. Meaning receive the email and try to send them to the primary as soon it has come up again.

I've tried to figure out things at qmail.org but found nothing about fallback. I guessed it's a matter of configuration.

Hopefully there's somebody who could get me on the right track.

You would configure your qmail server as a gateway server, which means the following key points...

in 'rctphosts', configure for the domains you wish to service.
in 'queuelifetime', configure a value of several days in order to allow your gateway server to keep mail in queue until your primary becomes available again
You should NOT define any domains in 'locals' or 'virtualdomains'
You probably SHOULD but may NOT HAVE TO use definitions in an 'smtproutes' file for delivery of the serviced domains to the primary mail server. I don't believe it's required, but it might help.

HEre's a link I dredged up googling, haven't explored much, but they might also have a turnkey kit for you
