Cause:
Authentication in BW 5.11 is more rigorous, which means authentication is required at the SMTP server.

Resolution

1). In command line mode, use the telnet command to see if the username and password is required when sending an email via an SMTP server. It will succeed even without providing a username and password. The SMTP server authentication is base on IP, which means if the IP of the request is in the allow list, the username and password is not required. This configuration will not work in BW 5.11


2). Change the authentication in SMTP server to "Basic Authentication".
