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, "<*****[email protected]>");
slist = curl_slist_append(slist, "<****[email protected]>");
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);
