Frequently asked questions about mail.de

I have problems logging into my email client (IMAP, POP3, SMTP - Outlook, Thunderbird etc.)

Here are the most common error messages and causes:

"Connection timed out" / "Server not responding"

Wrong server name (must be imap.mail.de / smtp.mail.de), wrong port (993/465/587), or temporary IP block due to brute-force attempts from your IP.

"Connection refused" / "Connection rejected"

Mostly wrong port or typo in the server name.

SSL/TLS/Certificate error

Wrong encryption (e.g. STARTTLS instead of SSL/TLS).

→ All correct settings + app-specific instructions:
