I was not using CURLOPT_CUSTOMREQUEST, nor was I setting CURLOPT_UPLOAD.
Setting CURLOPT_UPLOAD to 1L seems to have solved the issue of the VRFY
requests, and the output now reports that the mail was successfully sent (<
250 2.0.0 OK ...). The output is very much the same as with earlier
version of libcurl.

I'm not sure if the examples are actively maintained, but it might be a
good idea to add "curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);" to the
example here (and perhaps others?):
http://curl.haxx.se/libcurl/c/smtp-tls.html

Also, yes I was informed that I stupidly posted my base64 encoded login
information, and I have now changed my password. Thanks for the many
alerts.

Thanks for you help,

Kerry
