I'm assuming the best way to implement a backup mail server that will queue
mail in the event of a problem with the best MX would be to set the backup
server as 2nd MX (obviously), and then add all the appropriate domains to
rcpthosts.
Will that cause mail to be cached automatically, or is it
I'm moving all mail hosting from one server to another. I will stop SMTP on
server 1, move users mail to server 2, change DNS, start SMTP on server 2.
However, any mail sent in the time server1 is not receiving mail will be
remotely QUEUED. I don't want the mail to be ultimately delivered on
