I don't have an About/Checkup page on my installation, but the Settings/Troubleshooting page is no longer accessible - it returns a 403 Forbidden error when trying to access it. There is no way to define an authorised IP address to access this page.
I logged this as a ticket before seeing this thread and was told that the following was now the case:-
Access to this page is now limited to:
- Browsers accessing the server from the same local network (private IPv4 ranges), or\
- Authorized internal IPs used by SmarterTools
So basically, you only have access to this page if you are running your SmarterMail server on the same private LAN as your client PC or are on the SmarterTools network.
I have objected to this restriction as there is no way I can meet these restrictions as my server is housed in an external server centre and I use that page every time I upgrade to a new version to check that all functionality is working as expected.
I have suggested that the restrictions are wrong and that that page is of valid interest to all SmarterMail server admins and should be available to any of the admins listed on the Setting/Administrtors page, irrespective of IP address. I'm happy to accept that there is no reason I can think of why Domain Administrators or Users should have access to that page.
That proposal has now been "escalated this request by adding it to the product backlog"
