SSL Certificate Question

[geek876]

Hi,

I have a zimbra Server (single server) server1.mydomain.com with 2 Zimbra Domains, domain1.com and domain2.com. I have enabled SSL on the server. I want to have seperate certificates per domain. Is this possible? Currently clients access their emails using https://mail.domain1.com and https://mail.domain2.com. mail.domain1.com and mail.domain2.com both point to the IP address of Zimbra server server1.mydomain.com
The current certificate on the server is a self signed one wiht cname of server1.mydomain.com but I want per domain cert.

Thanks in advance
