SSL Certificates "invalid" although server says they are valid and correctly installed

I use Post email software. It has acknowledged that anti-virus programs can cause it to report that a valid SSL certificate is invalid. It has a work-around for both Kaspersky and Avast, but not for Bitdefender.


I have read in this forum messages about SSL certificates being found invalid dated from 2014-2017 that you can turn off the Scan SSL function in Bitdefender and that this may be a solution. Other messages say that this is not the case as the Scan SSL is set in newer Bitdefender versions to turn on by default even after you turn it off.

I do not know where to find the Scan SSL. Can you please help?

Thank you.
