Do you want to access your mail server from any browser? Yes you can. Click the “Configuration” tab, Select “e-mail”. The following screen should appear:
Click the “Change e-mail access settings” button and select “Allow HTTPS” in the Webmail access drop-down box and Save your changes:

Now send a test mail to another user. In our example, i send a test mail from “email@example.com” to “firstname.lastname@example.org”. Click “New Message” and enter recipient details and hit “send Message”:
Now log out from client1 and log in to client2:
Now the test mail will be received in the client2 user inbox.
Thats it. If you want to access your mail server using domain name instead of your ip address, you must configure this server as DNS Server or you add the MX records to your existing DNS Server.
