JangoSMTP now supports SSL/TLS

JangoMail has added support for SSL connections to our relay server from your email client of choice (e.g. Outlook, Thunderbird, Mac Mail, etc.). Just as when you use an HTTPS connection to connect to a website and make a secure online purchase, you can use the same technology to setup a secure connection with JangoMail and send email through your JangoSMTP account. This ensures your JangoSMTP username and password remain secure as they are transmitted between your computer and JangoSMTP relay servers. All that's needed to enable this feature a quick settings change in your email client.

Note: These instructions assume you already have your JangoSMTP account setup in your mail client. Follow these directions if you don't already have your mail client setup to send through your JangoSMTP account.

  4. Go to the Advanced tab

Most modern email clients support SSL/TLS. If your email client is not listed above, open up your account settings configuration page and find the outgoing email server connection settings. The option you want to enable will be called SSL/TLS (not STARTTLS). Also look out for a default connection port. Generally this port number will be 25 or 2525 before you setup SSL/TLS, but it should be changed to 465 after the feature is setup. When in doubt, submit a support ticket and a member of the JangoSMTP support team will be able to assist you in choosing the right options.
