.TH CURLOPT_MAIL_RCPT_ALLLOWFAILS 3 "January 14, 2020" "libcurl 7.69.1" "curl_easy_setopt options"

.SH NAME
CURLOPT_MAIL_RCPT_ALLLOWFAILS \- allow RCPT TO command to fail for some recipients
.SH SYNOPSIS
.nf
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAIL_RCPT_ALLLOWFAILS,
                          long allow);
.SH DESCRIPTION
If \fIallow\fP 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 \fIignore\fP to 1L which will
make curl ignore errors and proceed with the remaining valid recipients.

In case when all recipients cause RCPT TO command to fail, curl will abort SMTP
conversation and return the error received from to the last RCPT TO command.
.SH DEFAULT
0
.SH PROTOCOLS
SMTP

  list = curl_slist_append(list, "invalidemailaddress");
