CURLOPT_MAIL_RCPT_ALLOWFAILS(3) Library Functions Manual
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);
}
