Failover backup solution for IPswitch IMail
Posted on 2011-10-14
Hello, I recently joined a company and was named Email Administrator. We are running IPswitch Imail server v. 11.5 and it is running on a new box with Windows 2008 R2 64-bit. We host about 500 domains as well as about 5 of our own on this server with about 1000 users/email accounts. My issue is that to do ANY maintenance on the server or email system, I have to stop the email services and shut down email to 500 domains, unacceptable. The other issue is what if the server hardware fails, I am destined for being down for an unacceptable length of time to get back up and running. Anyways, I have gotten the financial greenlight to go ahead and pursue a failover system with email redundancy, the question is what? I do have an identical backup server that I would like to have mirror the original and be able to cutover to the backup server in case of disaster, maintenance, etc. How do I create a failover system with the IMail server and what products will work with this email system to capture all settings and registry? Thank you in advance for your suggestions!
