CURLOPT_MAIL_RCPT_ALLLOWFAILS(3)                      curl_easy_setopt options

NAME
       CURLOPT_MAIL_RCPT_ALLLOWFAILS - allow RCPT TO command to fail for some
       recipients

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAIL_RCPT_ALLLOWFAILS,
                                 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 will abort
       SMTP conversation if at least one of the recipients causes RCPT TO
       command to return an error.

       The default behavior can be changed by setting ignore to 1L which will
       make curl ignore errors and proceed with the remaining valid
       recipients.

       In case when all recipients cause RCPT TO command to fail, curl will
       abort SMTP conversation and return the error received from to the last
       RCPT TO command.

DEFAULT
       0

PROTOCOLS
       SMTP

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         struct curl_slist *list;

         /* 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_ALLLOWFAILS, 1L);

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

AVAILABILITY
