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.

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

DEFAULT

       0

PROTOCOLS

EXAMPLE

         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);
       }
