NAME

       CURLOPT_MAIL_RCPT_ALLOWFAILS - allow RCPT TO command to fail for some recipients

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAIL_RCPT_ALLOWFAILS,
                                 long allow);

DESCRIPTION

       If allow is set to 1L, allow RCPT TO command to fail for some recipients.

       When  sending data to multiple recipients, by default curl aborts the SMTP conversation if
       either one of the recipients causes the RCPT TO command to return an error.

       The default behavior can be changed by setting allow to  1L  which  makes  libcurl  ignore
       errors for individual recipients and proceed with the remaining accepted recipients.

       If  all  recipients  trigger  RCPT TO failures and this flag is specified, curl aborts the
       SMTP conversation and returns the error received from to the last RCPT TO command.

DEFAULT

       0

PROTOCOLS

       This functionality affects smtp only

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           struct curl_slist *list;
           CURLcode res;

           /* Adding one valid and one invalid email address */
           list = curl_slist_append(NULL, "person@example.com");
           list = curl_slist_append(list, "invalidemailaddress");

           curl_easy_setopt(curl, CURLOPT_URL, "smtp://example.com/");
           curl_easy_setopt(curl, CURLOPT_MAIL_RCPT_ALLOWFAILS, 1L);

           res = curl_easy_perform(curl);
           curl_slist_free_all(list);
           curl_easy_cleanup(curl);
         }
       }
