Topic: Setting backup MX server

Hi ..

I have successful installation and running of iredmail server. Thank you Zhang for all your help.

Now I want to setup a backup mail server. What will be the steps?

I have one more server running using ISPConfig. Using Postfix, Dovecot, Spamassain, amavisd. Can I use that server for backup of iredmail domains?

Here's offical tutorial:

If you can't query virtual mail domains/accounts from backup mx, then leave "relay_recipient_maps =" as empty. It will accept all mails for relay domains. including mails sent to non-exist mail accounts.

Here's another tutorial with more details and explaination:

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?
