Important notes: The mail server with which the SAP system is both the input and the output side connected must be equipped with appropriate virus scanners and spam filters. It is recommended to separate the reception socket through the firewall to the outside, so that no delivery can be made by third parties. It is further recommended that the output side does not communicate directly with a mail server outside the firewall. These instructions may vary slightly in different SAP releases.

  • Set indicator “node in operation“
  • Mail Host: Here you enter the IP address or host name of the mail server
  • Mail Port: Usually, 25 or 587
  • Supported address types: Internet and address the “*”. In order for this node is used for all e-mail addresses

FAQ SAP Standard
