SMTP ports outgoing (25 , 465, 587)

Customers with external mail servers should be aware of the following.

Shipping via the port

  • 25

is deactivated for internal and external use on all systems. (Independent of the display of the cPanel interface)

If you need to access external mail servers, you can use the secure ports

  • 587
  • 465


If you use a provider for sending mail which requires port 25, change the provider! Also on request we do not allow unencrypted connections in your own interest and that of your customers / users!
