Solved SMTP Server Not working

[flogli]

Greetings, this evening I noticed that SMTP server is not working and email notifications are not being sent on Version 20.0 Update 3.
Access certificate is not generated.

I tested on two different systems with the same result on 3CX SMTP and also Microsoft 365. Is anyone else seeing this?

I am getting this errror:
The remote certificate was rejected by the provided RemoteCertificateValidationCallback.

3CX have just responded to us that they are investigating and are aware of issue.

@Liam_AfterDark @Jay K This has been resolved, can you please also check from your side?

Thankyou, test was successful.
