How do I redirect http to a https general URL?

[henryw]

Hi Everyone,

My very first post to Zimbra forum.

I am running Zimbra Release 5.0.8_GA_2462.RHEL5_64_20080709155301 RHEL5_64 NETWORK edition.

I have serval customers using Zimbra using the following method:

Company A: http://mail.companya.com
Company B: http://mail.companyb.com
Company C: http://mail.companyc.com
etc..

My main zimbra server domain is http://zimbra.mycompany.com. To avoid purchasing individual SSL certificate for each URL and allocate unique IP addresses, I purchased a SSL certificate for domain (https://zimbra.mycompany.com)

How do I configure Zimbra so that all customers will automatically redirect to https://zimbra.mycompany.com when typing their current domain name for their respective company? Thank you
