Answer
GMS Secure Socket Layer has returned an error to the remote server’s AUTH command because GMS has been configured to only accept messages encrypted by the secure socket layer (SSL ) from this remote system. No communication between the remote server/client and GMS will be possible until the remote server correctly negotiates a secure connection. GMS uses the standard secure transport specified in RFC2487 to ensure compatibility with other messaging servers.
In this case, session Undefined is processing a connection from Undefined which gave the SMTP command
Undefined
GMS rejected the command with
Undefined
To resolve this problem, make sure that
- GMS has the correct certificate installed;
- the remote server or client conforms to the SSL or STARTTLS standard; and
- the remote server or client is correctly configured.
