Server Certificate does not match the name of the server at Yahoo.com

When setting up a new email account using eM Client version 6.0.21032.0:

eM Client can’t verify the identity of “carddav.address.yahoo.com
The host name doesn’t match the name specified in the certificate.
You might be connecting to a server that is pretending to be “carddav.address.yahoo.com” which could put confidential information at risk.

I viewed the certificate and it seems to be authentic but I am no expert on cyber security. Any Ideas?

Hi, this means the yahoo settings may have been changed and the application is receiving a certificate for a different domain, however in this case I believe there’s nothing to worry about and you should be able to connect to the server using the “connect” button and using the “remember setting” option included in the displayed window.

Thank you,
Paul.
