.SH NAME
CURLOPT_MAIL_RCPT \- list of SMTP mail recipients
.SH SYNOPSIS
.nf
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAIL_RCPT,
                          struct curl_slist *rcpts);
.fi
.SH 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
\fBstruct curl_slist\fP structs properly filled in. Use
\fIcurl_slist_append(3)\fP to create the list and \fIcurl_slist_free_all(3)\fP
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 (\fBVRFY\fP command), each recipient
should be specified as the user name or user name and domain (as per Section
3.5 of RFC 5321).

When performing a mailing list expand (\fBEXPN\fP command), each recipient
should be specified using the mailing list name, such as "Friends" or
\&"London\-Office".
