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 result;

    /* 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);

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