SMTP outbound authentication does not support CRAM-MD5?

Hi,

can anyone confirm that the CRAM-MD5 authentication method is not supported for SMTP outbound authentication in Domino 8? Even I restrict our mail relay to CRAM-MD5, Domino tries to use the LOGIN method, which is not acceptable because the password is not encrypted but just Base64-encoded.

Thanks in advance,

Tobias
