Dear Zimbra community,
I have been using zimbra for a little while and love it. I'd like to host my family emails and seeing how that goes, maybe expand to my existing customers. I have a good basic understanding of mail servers but I lack knowledge in redundancy settings.
I'd simply like for my family/clients to be able to still get/send emails if the mail zimbra server is down for maintenance. I think a cluster is a bit too far fetched for a small setup with a few domains so I'm looking for ideas and pointers to relevant documentation.
I get how I'd do this with postfix, etc ... but zimbra is a complete solution and I'm a little confused on how to get it done.
Many thanks for any information you might have for me.
