How can I make it so that my emails are sent and received securingly using encryption?

If you want to encrypt your emails (use SSL) you will need to know 2 things:   your official QWK.net email server name and which email protocol you are using.

1 - To find out which QWK.net email server your email is on you will need to log in to the QWK.net Control Panel.
    - Click on the "Domains" icon.
    - Click on the "Edit" icon associated with the domain in question.
    - Click on the "Edit" icon for 'DNS Configuration'.
    - The official QWK.net email server name can be found in the 'Data' column under 'Built in MX records'.

    NOTE:  It will be one of the following:
        - hsmail.qwknetllc.com
        - mail.qwknetllc.com
        - mail1.qwknetllc.com
        - mail2.qwknetllc.com
        - mail3.qwknetllc.com
        - mail4.qwknetllc.com
        - mail5.qwknetllc.com

2 - To find out which protocol you are using, simply get into the email account settings for the email address in question and you will see one of the following under the "Account Type" section:  POP   or   IMAP.  As an example, here are directions on how to find the protocol in Outlook 2010/2013:
    - In Outlook, click on the "File" tab,
    - Click on "Info",
    - Click on "Account Settings",
    - Then from the drop down, click on "Account Settings… Add and remove",
    - Then in the new window "Account Settings", you will see "Type" in the middle.  Here is where you will see if your account's protocol is either POP/SMTP or IMAP/SMTP.

========================================================================================

Once you have this information, all you have to do is make sure your Incoming and Outgoing mail servers are the official QWK.net email server names found in step one and that your email protocol is using the correct port numbers.

If you are using POP, change the port numbers from:
    - 110   to   995
    - 25/587   to   465

If you are using IMAP, change the port numbers from:
    - 143   to   993
    - 25/587   to   465
