Disable TLS Security

Hello everybody,

I try to set up a SMTP Connection and get the following error:

"error": "Hostname/IP doesn't match certificate's altnames: \"Host: is not in the cert's altnames:,\""

There is a problem with the certificate of the Domain and the Subdomain which I can not resolve.

Is it possible to deactivate TLS Security?


No, for custom SMTP providers the requirements listed at ( include the support of TLS with a certificate signed by a public certificate authority and this cannot be disabled.
