How to Install Cert for Domain for Webmail Interface

[the_griz]

My desired configuration is:

Zimbra Server: mail.mydomain1.com running email services for 2 domains: mydomain1.com and mydomain2.com.

I obtained 3 commercial certs:
- 1 for mail.mydomain1.com,
- 1 for webmail.mydomain1.com and
- 1 for webmail.mydomain2

I installed the cert that matched the Zimbra server's name: mail.mydomain1.com and that works well.

I have http://webmail.mydomain1.com and http://webmail.mydomain2.com working well. However, I want to force these to use https:// and my 2 certs that match the names.

The issue is: where are the two webmail interfaces configured? /opt/zimbra/httpd/httpd.conf is pretty much bare. I know who to associate http with a domain but I want to make sure I am editing the right conf. I cannot even find where port 7071 for the admin root is configured at!

I appreciate all help so much!
Thanks!
