POP3 Accounts with SSL: Invalid Security Certificate

POP3 Accounts with SSL: Invalid Security Certificate

Hello Zoho team,

different providers (freenet.de and web.de) are telling me that they are switching to SSL this month. So I have to enable SSL when I want to get the mails with your service. But when I'm trying to "Use SSL" on Port 995 your service tells me
"Invalid Security Certificate for the Server. Please change the incoming port to 110 and retry configuring."

In different forum posts I'v read that in these cases you also have to do something about that!?

Would you please have a look at the problem and help me? 

Thanks for the effort!
Enrico
