Zimbra is running on the subdomain zimbra.mydomain.com with zmtlsctl set to redirect
All seems to work fine apart from one issue
When I use IE6/8 (most of my users will use IE) and click on the Documents tab I get a warning :
Do you want to view only the webpage content that was delivered securely?
This webpage contains content that will not be delivered using a secure HTTPS connection which would compromise the security of the webpage.
If click "Yes" it causes formatting issues.
This only happens with IE
Apart from disabling Documents (which I don't want to do - the Documents tab is useful) or advising users to click "No" (generally a bad plan) I don't know what to do.
