# NAME
|
||
|
|
|
||
|
|
CURLOPT_MAIL_RCPT - list of SMTP mail recipients
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#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.
|
||
|
|
|
||
|
|
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`.
