[牟林海]

Hello
When I use smtp to send mail, there will be following the situation, before the use of no such situation, I think that not sending HELO to continue to the other¡£
This is the code I write, is there a mistake?

curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
curl_easy_setopt(curl, CURLOPT_HEADER, 1L);
curl_easy_setopt(curl, CURLOPT_USE_SSL, CURLUSESSL_ALL);
curl_easy_setopt(curl, CURLOPT_URL, "smtp.gmail.com");
curl_easy_setopt(curl, CURLOPT_PORT, 25);

curl_easy_setopt(curl, CURLOPT_MAIL_FROM, "<********@gmail.com>");

slist = curl_slist_append(slist, "<*******@gmail.com>");
curl_easy_setopt(curl, CURLOPT_MAIL_RCPT, slist);

curl_easy_setopt(curl, CURLOPT_USERNAME, "*******");
curl_easy_setopt(curl, CURLOPT_PASSWORD, "********");
curl_easy_setopt(curl, CURLOPT_READDATA, fp);
curl_easy_setopt(curl, CURLOPT_READFUNCTION, read_data);

The mistake is in this line: the value you set is not a URL. Therefore,
curl guesses what protocol you're asking for and in this case it guesses
wrong. Use an SMTP URL here, like smtp://smtp.gmail.com

Then you probably have two libcurls installed. One older version that your app
seems to link against and one newer that your command line tool uses...
