In the last few days I have described the structure of a small Exchange organization as I use it privately. To make it easier to find the articles again, here is an overview of the articles:
- Part 1: Installation Active Directory and configuration DNS
- Part 2: Installation Exchange Server 2016 CU 2
- Part 3: Exchange Server configuration incl. certificate
- Part 4: Configuration Sophos UTM 9.4 and Exchange Server for receiving / sending e-mail
- Part 5: Configuration Exchange Webservices, Sophos UTM, Fritzbox
However, I received an e-mail with an interesting question from which I would like to quote briefly:
I would like to rebuild the environment like this, at the moment we are only a small company with a relatively limited budget for IT, we have so far managed with a NAS as a „server“, but we are slowly reaching its limits and want to buy a corresponding server. However, as we are also growing rapidly and may buy another company, I wonder whether it is possible to expand this example configuration even further in terms of availability and a higher number of users?
I think that's a very good question, because the requirements for your own infrastructure can certainly change from time to time.
I have therefore thought about the following, the small Exchange organization will be expanded in the next articles:
Sophos UTM, Domain Controller and Exchange Server will be designed redundantly. The switch from POP3 retrieval and dynamic IP to static IP without a smart host at the provider will also be an issue.
However, I'm going on vacation first, then I'll tackle the issue.
