How to create a permanent redirect for MailEnable WebMail from HTTP to HTTPS?

Answer

Note: implement this method for domains where you want to use https connection to MailEnable by default.

1. Go to Start > Windows Administrative Tools > Internet Information Services (IIS) Manager > server name > Sites > MailEnable WebMail > on the right side of the panel press Bindings > Add button

2.  Add the following records for the domain which will use https connection by default to MailEnable and then press OK:

• Type: http
• IP address: All Unassigned
• Port:80
• Hostname: webmail.example.com

3.  Choose MailEnable Webmail from Sites menu > press Explore > Open web.config file in text editor > paste the following code right before </system.webServer> :

<rewrite>
 <rules>
   <rule name="Redirect to HTTPS" enabled="true" stopProcessing="true">
    <match url="(.*)" />
     <conditions>
      <add input="{HTTPS}" pattern="off" />
      <add input="{HTTP_HOST}" pattern="(webmail)\.example\.com" />
     </conditions>
    <action type="Redirect" url="https://{C:0}/{R:0}" redirectType="Permanent"/>
   </rule>
 </rules>
</rewrite>

Where example.com is a domain name.

4. In Internet Information Services (IIS) Manager navigate to MailEnable Webmail site and press restart.
