With Telnet you can check whether you can reach our email server from your PC.
Please note:
On Windows operating systems, the Telnet client has been deactivated by default since Windows Vista. You must therefore activate it first:
- Windows 7
http://support.microsoft.com/kb/978779/de - Windows 8
https://support.microsoft.com/de-de/help/2801292 - Open Windows 10
1, click Programs and Features
2, click Enable or disable Windows features.
3, check Telnet Client.
4, click OK.
Please enter the command telnet, the server name and the server port in the command prompt or in the terminal.
Here are examples of what a successful Telnet connection on our IMAP, Pop3 and SMTP servers under Windows looks like.
