I hope the following could be a comment to this case:

SMTP auth fails because the SMTP server identifies only the first part
of the string (delimited by new line characters) as a response from the 
client, and the rest as distinct commands.

In my case, the response string is 80 characters long.  Without the
no-line-break option for base64-encode-sting, only the first 76 characters
are taken as a response to the server, and the authentication fails.
