I can not get Mails from mail.de by imap.

I changed the password for my mail account at mail.de. But now I can not get my mails by imap. Please help me.

Did you change your password in the settings of the EM-Client, too?
Sometimes it takes a while for the IMAP connection to work again.

Does an error message appear when the EM client attempts to connect to mail.de?
