We got a dedicated server with two IPs. Unfortunately, one of them is used to point to a shared SAN, so we have just the one other IP to use for both Webmail and secure POP/IMAP/SMTP services.
Is there a way in Zimbra to configure non https requests for a customer webmail domain (say, http://mail.customerdomain.com) to redirect to the https webmail url of the server (https://mail.primarydomain.com)?
At the moment, it automatically redirects to https://mail.customerdomain.com and throws an obvious SSL error. Because of the single IP limitation, we are unable to provide an SSL per customer domain.
Any help will be greatly appreciated.
