libcurl-7.34.0 was released on December 17 2013 [1]. Starting with this
version, SMTP requires CURLOPT_UPLOAD option [2]. If CURLOPT_UPLOAD option is
not set, libcurl emits VRFY command and no email is sent. [3]

Fix:
- Add 'p.curl.set(CurlOption.upload, 1L);' to std.net.curl.SMTP.initialize
or
- Add 'smtp.handle.set(CurlOption.upload, 1);' to user code. Example.
auto smtp = SMTP("smtps://smtp.gmail.com");
smtp.handle.set(CurlOption.upload, 1);
...
smtp.perform();
