Zoho Mail can accept certificates?

Zoho Mail can accept certificates?


Hi everyone.

I'm trying to connect to a POP account of my email of the Faculty through Zoho Mail but Zoho Mail always give this error:
" Problem in connecting to the mail server".

I repeated this process many times and I'm sure that all the fields are well filled. But I think that the problem is that this email service that I'm trying to connect, ask always to accept a certificate. Maybe Zoho Mail is not accepting this certificate? The certificate can be accessed here: http://mail.isr.uc.pt/certs/

Can anyone help me?

Thank you very much.
