Using HTTPs with webmail

Question

If I use HTTPs with webmail it seems it pulls the whole site to HTTPs. That is to port 4xx.
Is this assumption correct?
If so. Would the solution then be to create a new site entry in the webtab for webmail only to prevent our regular website from being pulled to port 4xx.
And then create an entry like webmail.mydomain.is in the DNS.
If so is it possible to let the external mail relay server retrieve data from the internal server or would it be logical to point the DNS entry to the internal servers HTTPs port?

The "Webmail" check box just creates an alias so that if that site has /webmail in the URL, it accesses the squirrelmail directory (usr/share/squirrelmail).
Here's my preferred setup:
- Assumes your server fqdn and your ssl cert common name are: mail.domain.com
- Open 80 & 443 in firewall/nat
- Create a site for mail.domain.com.
Port 80
No Options Checked (not webmail either)
In the Alias tab, add a redirect (the lower box)
Type: Redirect
Pattern: /
Path: https://mail.domain.com
(notice above is https)
- Create another site for mail.domain.com and the squirrelmail login.
Port 443 (SSL)
Path: /usr/share/squirrelmail
Be sure to select your IP address, don't leave it on <any>
Options: none
Setup your certificate
Now, when you go to:
http://mail.domain.com
you will be automatically redirected to:
https://mail.domain.com
