I am confused about using certs in ams. Maybe I'm just missing something. Here’s the issue:
I have ams 2.61 set up on a single server, behind a single public IP address. I am serving three domains (well, three registered domains). So, I created three self-signed certs, one for each domain, using the integrated ams function for doing so. I see all three certs listed in the “SSL Certificates†portion of the setup, so I think that worked. Now, in the WebMail setup, I seem to be able to select only one of the three certs. (I have “Use implicit SSL†checked; explicit SSL is grayed out and designated as unavailable.) I have also looked in the domain settings and see no options there.
Is there any way that I can adjust this on a per-domain basis? I had imaged that the web mail service would examine an incoming request header, extract the Host: element, and apply a cert accordingly, falling back to a specified default if required – or something like that. Instead, it appears to be applying just the one cert, no matter which domain I connect to from the Internet. I would prefer to keep the domains logically isolated if possible, using multiple certs, rather than using just one "catch-all" cert. After all, why else would multiple certs be supported at all?
What am I missing?
