Cannot resolve certificate errors - send emails using our SMTP server

Dear experts,


To be able to send emails using our SMTP server, I have installed a certificate on my client machine (Windows 10). The certificate is not expired. It is issued by Go Daddy Secure Certificate Authority - G2. I can see that I have it installed also. I use the right certificate name. And yet I keep receiving errors:


System.Net.Security.SslPolicyErrors.RemoteCertificateNameMismatch | System.Net.Security.SslPolicyErrors.RemoteCertificateChainErrors

A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider.

Could you please help and guide me to fix this issue?



Hi @dpreznik,


Thanks for posting. Are you trying to install it on a 3rd party server? Feel free to provide more details on the type of hosting you have so others in the Community can offer suggestions.
