Hi.I tried int his example code.But it doesn't runs:
[code]
#include <stdio.h>
#include <string.h>
#include <curl.h>
/* This is a simple example showing how to send mail using libcurl's SMTP
* capabilities. It builds on the simplesmtp.c example, adding some
* authentication and transport security.

"It could be a lot of lines, could be MIME encoded, whatever.\n",
"Check RFC5322.\n",

memcpy(ptr, data, len);

* Instead, you should get the issuer certificate (or the host
certificate

certificates
* that are known to libcurl using CURLOPT_CAINFO and/or CURLOPT_CAPATH.
See
* docs/SSLCERTS for more information.

/* Since the traffic will be encrypted, it is very useful to turn on
debug
* information within libcurl to see what is happening during the
transfer.
