Dear All;
I configured the bases on the document http://scn.sap.com/docs/DOC-46513
I finished all the mentioned steps, but when I try to send an email from the system itself I get the error: cannot be sent: 503 you must authenticate first (#5.5.1) as you can see below:
Kindly let me know how I can fix this error.
Best Regards
