Importing POP3 Mails: Invalid Security Certificate for the Server.

Importing POP3 Mails: Invalid Security Certificate for the Server.

Hi,

I would like to add my company mail adress to Zoho Mail.

Our mailserver provides a valid, officially signed SSL zertificate for POP3 / Port 995, but the dialog tells me "
Invalid Security Certificate for the Server. Please change the incoming port to 110 and retry configuring.".

Can you help me finding the problem, since this error message does not tell me any detail.

If I connect to our mailserver and read the certificate using openssl on the commandline, it tells me we have a valid certificate signed by thawte. I can add the server to any e-mail client without problems.

Thank you!
