Few Queries before setup

[dipeshmehta]

I am planning to deploy on-premises ZCS FOSS into my small business scenario. At this point I have few doubts in my mind (might not fully relevant with zimbra) need to rectify.

1. At present our mails are hosted on Service Provider's server. I understand that, after setting up ZCS for the same domain, alongwith setting up mx priority for ZCS, mails from outside shall come to ZCS server. My question is: during setting up the things, for any particular incoming mail, if recipient not found on my Zimbra server, will it be delivered to 2nd mx priority i.e. hosted servers?

2. As being small business, we do not have redundant internet connectivity. By any means, if connectivity fails, what shall happen to incoming mails? means, shall they be waiting for server to become available? in other words, how much time usually mail stays in queue at senders server?

3. I understand that I can use Zimbra for more than one domain. Can I create different administrator for each domain?

Thanks in advance.

No, the email would be completely rejected and sent back to the sender. There are ways to get around this but the easiest solution is to ensure you create all the email addresses in advance

Inbound emails would be queued on the sending MTA for a duration that they have sent; could be 5 days could be 1 hour. With that it mind it would be prudent to set up a secondary MX service. Plenty of them exist but my personal preference is DynDNS.com - Free Domain Name, Managed DNS, Email Services

Multiple domain administrators is a feature of the Network Edition Zimbra - Compare Products

Thanks in advance.

I already have hosted email solution, and if I continue to use it after zimbra deployed so if connectivity to my zimbra breaks, the mail shall be delivered to secondary mx servers. Can you guide me how to retrieve such inbound mails to my ZCS after connectivity established back.
