+.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
+.SH EXAMPLE
+.nf
+CURL *curl = curl_easy_init();
+if(curl) {
+  struct curl_slist *list;
+
+  /* Adding one valid and one invalid email address */
+  list = curl_slist_append(NULL, "[email protected]");
+  list = curl_slist_append(list, "invalidemailaddress");
+
+  curl_easy_setopt(curl, CURLOPT_URL, "smtp://example.com/");
+  curl_easy_setopt(curl, CURLOPT_MAIL_RCPT_ALLLOWFAILS, 1L);
+
+  ret = curl_easy_perform(curl);
+  curl_slist_free_all(list);
+  curl_easy_cleanup(curl);
