# NAME
|
||
|
|
|
||
|
|
CURLOPT_MAIL_RCPT_ALLOWFAILS - allow RCPT TO command to fail for some recipients
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#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.
