Our SMTP department uses the security feature „TLS“ but we don’t use a separate User/Password for authentication.
This is done due a check if the sending servername (FQDN) is enabled for sending mail’s.
Within the kiwi application it is mandantory to use User/Password if security is enabled.
Our feature request based on using security without User/Password.
Therefore we open a ticket in 08.2022 with no response until now.
It would be nice if you can finish this 
At the moment the application is not full usable to our request’s
