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 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

         /* 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);

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