2. Choose “Email Account”. Click Next.
3. Enter your name and email address. Click Next.
4. Choose POP, set Incoming & Outgoing Server to: mail.secure-by-design.com. Click Next.
5. Incoming User Name. Click Next, as the default is correct.

7. Uncheck “Download messages now”. Click Finish.

This configures the basic settings for your account.  You will also need to enable the SSL encryption settings for it to work:
