The mail server told you to use TLS. :-)

So try the curl flags --ssl or --ssl-reqd.

If that works set CURLOPT_USE_SSL to CURLUSESSL_TRY or CURLUSESSL_ALL.
(See http://curl.haxx.se/libcurl/c/curl_easy_setopt.html,
even this option is filed as FTP option it should work with other protocols
too, if I remeber correctly...)

Message generation is not a job of curl. Either build
the message by your self (read the RFC) or find a library for that,
I'm not aware of any C library (only Perl, Java and PHP).
