Problem

Your connection to this server is not encrypted.

This means that people who have access to the computer you are using, or any computer in between the one you're using and this webmail server, can listen in on everything you send or receive.

Solution

This mail server provides all necessary services through SSL encrypted connections:

Secure webmail
Secure mail administration

For those of you who use IMAP, SMTP and POP3 connections, these are all available with SSL encryption.
