Situation
GWIA is setup for SMTP SSL enabled or required but no SSL connection is created when sending out email to SMTP server that support STARTTLS
Resolution
For SMTP to setup a secure SSL connection both SMTP servers must have a certificate and key file, when the GWIA does not have a certificate and key file defined in gwadmin in the SSL Settings menu you need to generate this first with the button "Generate Certificate"
After the GWIA is restarted a secure SSL connection can be created with external SMTP servers.
