SUMMARY

SSL support is available for Microsoft IIS.  This article contains information for configuring this.

DETAIL

SSL needs to be implemented for the IIS web site that is configured with the web mail virtual directory (as created under Services Webmail in the MailEnable Administration Program).

The way SSL is implemented means that a separate IP address is required for each SSL domain that is hosted i.e.: it is not possible to use host headers and a single IP address and use SSL.

Each domain that has SSL configured requires IIS to use a separate IP address for that web site.
