Your e-mail can be sent via webmail or with an e-mail client like Mozilla Thunderbird, MS Outlook or Apple Mail. The following example configures the e-mail client Thunderbird with STARTTLS. Proceed as follows: select New -> Existing E-Mail Account in the menu enter your name, e-mail address and password. The “connection data” can be found in your Control Panel. Click on “Continue”. Thunderbird will now try to figure out the locations automatically.
