I have successfully setup an EC2 server for some redundancy.
My question is, what is the best solution to keep this backup server up to date w/ newly created accounts and emails efficiently. I have run across a few scripts to get it up to date, but how do you keep it up to date?
The most likely scenario initially looks like I will need to use imapsync and synchronize the servers data. But that doesn't seem realistic as you add email accounts to constantly run that and update the script with the list of emails every time you add someone new.
Once you have the servers synced initially, what is the best way to keep them in sync and up to date?
Any advice you can provide would be greatly appreciated.
