이것은 내 libcurl 코드입니다. 나는 리눅스에서 내 자신의 이메일 도메인에 이메일을 보내려고합니다.libcurl을 사용하여 전자 메일을 보내려는 인증서 문제
이것은 내 샘플 libcurl 코드입니다.
curl_easy_setopt(curl, CURLOPT_USERNAME, "[email protected]");
curl_easy_setopt(curl, CURLOPT_PASSWORD, "mypassword");
curl_easy_setopt(curl, CURLOPT_URL, "smtp://mail.mydomain.com:25");
curl_easy_setopt(curl, CURLOPT_USE_SSL, (long)CURLUSESSL_ALL);
curl_easy_setopt(curl, CURLOPT_MAIL_FROM, FROM);
recipients = curl_slist_append(recipients, TO);
curl_easy_setopt(curl, CURLOPT_MAIL_RCPT, recipients);
curl_easy_setopt(curl, CURLOPT_INFILESIZE, file_size);
curl_easy_setopt(curl, CURLOPT_READFUNCTION, fileBuf_source);
curl_easy_setopt(curl, CURLOPT_READDATA, &file_upload_ctx);
curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);
curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L); //Dont display Curl Connection data Change 1L to 0
res = curl_easy_perform(curl);
