CURLOPT_MAIL_RCPT(3) Library Functions Manual CURLOPT_MAIL_RCPT(3)
NAME
CURLOPT_MAIL_RCPT - list of SMTP mail recipients
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAIL_RCPT,
struct curl_slist *rcpts);
DESCRIPTION
Pass a pointer to a linked list of recipients to pass to the server in
your SMTP mail request. The linked list should be a fully valid list of
struct curl_slist structs properly filled in. Use curl_slist_append(3)
to create the list and curl_slist_free_all(3) to clean up an entire
list.
libcurl does not copy the list, it needs to be kept around until after
the transfer has completed.
When performing a mail transfer, each recipient should be specified
within a pair of angled brackets (<>), however, should you not use an
angled bracket as the first character libcurl assumes you provided a
single email address and encloses that address within brackets for you.
When performing an address verification (VRFY command), each recipient
should be specified as the username or username plus domain (as per
Section 3.5 of RFC 5321).
When performing a mailing list expand (EXPN command), each recipient
should be specified using the mailing list name, such as Friends or
London-Office.
Using this option multiple times makes the last set list override the
previous ones. Set it to NULL to disable its use again.
DEFAULT
NULL
