- Added a warning for users who attempt authentication on servers that don't allow STARTTLS (they are transmitted in plain text)
- Included a note when AUTH fails due to no supported mechanisms including the mechanisms supported (PLAIN and LOGIN)
- If the STARTTLS extension is advertised we automatically STARTTLS before authenticating or sending
- Uses the secure config key to determine if we should verify the cert. By default it does not verify the cert (should not break any configs)
- Attempt auth when the config has a SMTP password and the server supports the AUTH extension and either the PLAIN or LOGIN mechanism
- Check the mechanisms supported by the server and use PLAIN or LOGIN depending on which is supported
- Changed secure key to use boolean values instead of strings
- Arranged SMTP notifier properties/vars to be in the same order
- Log the steps for STARTTLS (debug only)
- Log the steps for AUTH (debug only)
