My Zimbra server server's canonical name is aegir.thatonedomain.com, and webmail is a cname.
I'd prefer to access the web interface by hitting https://webmail.thatonedomain.com, and that works fine - so long as I don't try to access my briefcase or any of my documents. When I do that, the host name in the URL changes to aegir. I can still connect, obviously, but my SSL cert is for "webmail", and my browser throws a cert error.
Is there an easy way to make the host name in the URL "stick" to 'webmail'?
On a "normal" Apache server, I'd make this work with a mod_rewrite rule and / or by way of creating a <VirtualHost> configuration, but I'm afraid to play too much with the default Zimbra config.
