contact Mail.de

Hello,
I try to connect to a German E-Mail Provider but I can´t get contact. There is no error in MailMate.
Is it possible to get information in MailMate to get an information witch answer it get from the server?

The support from Mail.de give us information about the connection and I use it in MailMate.

But there is no contact to the server.

Do you have any information to help?
