[IMail Forum] How to ensure high availability of email service using Imail 2006?

[Cathal O'Donnell]

Hello everyone, I am looking for detailed information and recommendations on how to deploy Imail 2006 in such a way to guarantee the high availability of email service. I have read about one method by using a backup server with a lower MX record to act as store and forward. Are there any other methods /system designs such as replication or clustering that anyone has been successful with? Regards Cathal
