-Currently SASL security layers are not supported for SMTP.

-SMTP SASL code
-will always negotiate an unencrypted connection. This means that while the SMTP
-authentication can be encrypted, the subsequent data stream can not. This is in

-.BR nmh 's
-POP3 SASL support, where encryption is supported for both the
-authentication and the data stream.
+If SASL authentication is successful,
