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 username or username plus 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 \fIFriends\fP or \fILondon\-Office\fP. .SH DEFAULT NULL .SH PROTOCOLS SMTP .SH EXAMPLE .nf int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode res; struct curl_slist *list; list = curl_slist_append(NULL, "root@localhost"); list = curl_slist_append(list, "person@example.com"); curl_easy_setopt(curl, CURLOPT_URL, "smtp://example.com/"); curl_easy_setopt(curl, CURLOPT_MAIL_RCPT, list); res = curl_easy_perform(curl); curl_slist_free_all(list); curl_easy_cleanup(curl); } } .fi .SH AVAILABILITY Added in 7.20.0.
