Hi Team,

I am in the process of setting Iredmail on a site that has a poor internet connection so they are using a satellite connection. There is windows 2016 and I have intergrated it with Irdemail. The issue is due to connection going down every so often,  I wanted if there is a way to have 2 Iredmail running in an active active cluster where if the primary one goes down due to internet connection mail will be delivered to the second one and as soo as the 1st one comes back up all the emails will sync.
On a normal day email so be sync on both servers.

As this is not live yet, I can even remove intergration with active directory if needed.

The second mail server will be at a different site. There would be a site to site vpn so that could be used to sync possibly.

Please advise.

Cheers,

Rajbps
