We have sent with this API an automatic generated e-mail from a non existing sender address no_reply.....@sap.com to an existing external e-mail address. The response is "sent with o.k." although no e-mail is sent. (I assume no e-mail is sent because the recipient receives no e-mail). At the moment this e-mail vanish.
The question:
is a API documentation available regarding the response handling of this API? In which case I get back which response? Or is this a question of the mailserver customizing? Or is the usage of this API restricted - some preconditions existing?
Any help is appreciated.
Our further investigations:
This combination is working:
valid .....@sap.com sender address to valid ...@sap.com recipient address
valid .....@sap.com sender address to valid ...@external recipient address
non existing ..no_reply@sap.com sender address to valid ...@sap.com recipient address
In all of these cases the response of the API is "sent with o.k."
This combination is not working:
valid .....@sap.com sender address to invalid ...@sap.com recipient address
In this case is the response: "Exception: Error: error couldn't send RCPT header Stack Trace....."
