i had this experience using an Exchange SMTP (onprem) and i always got
PKIX path validation failed: java.security.cert.CertPathValidatorException: The revocation status of the certificate with subject (CN=xxxx, OU=xx) could not be determined.
even 100% sure using the right trusted Certificate. As workaround i built an additional internal receive connector:25 on exchange without TLS and just trusted IP from Breeze-sm100 IP. That worked for me...

hope that helps...

Is there a way to post the recording.wav to an webdav http srv with at least basic authentication. I didnt find a way to add usr/pwd in the URL. Reference Doc an help doesn't state that there is something possible without a workaround.

thx in advance.
