Mail Client auto Configuration to use SSL/TLS

Good Day Guys,

When Thunderbird (for example) queries my server with the default mail auto-configure or the XML below; both auto populate the SMTP settings to "no encryption". If I change Thunderbird to use encryption it works fine but how can I tell this XML script to offer SSL or StartTLS to begin with?

Any help would be greatly appreciated!


Current XML Data for Thunderbird:

<?xml version="1.0" encoding="UTF-8"?>
<clientConfig version="1.1">
  <emailProvider id="$SMTP_DOMAIN">
    <displayName>$OWNER Email</displayName>
    <incomingServer type="imap">
    <outgoingServer type="smtp">

Current XML data for OUTLOOK:

<?xml version="1.0" encoding="utf-8" ?>
<Autodiscover xmlns="">
  <Response xmlns="">

You need to enable TLS, then install a certificate to be used, Mine is from Let's Encrypt which needs a manual "renewal"/"copying" from my auto renew certificate (main domain).

Encryption is not being pushed if you have an invalid certificate.

Hi coderinthebox,

I have a Comodo wildcard attached that is working. If I change the XML

<socketType>$SMTP_TYPE</socketType>     to read      <socketType>$SMTP_SSL</socketType>

Then the autconfigure sets it to STARTTLS but the login name then populates with only the username and not username.domain as it does with no encryption...
