The linked list should be a fully valid list of 32**struct curl_slist** structs properly filled in. Use curl_slist_append(3) to 33create the list and curl_slist_free_all(3) to clean up an entire list. 34 35libcurl does not copy the list, it needs to be kept around until after the 36transfer has completed. 37 38When performing a mail transfer, each recipient should be specified within a 39pair of angled brackets (\<\>), however, should you not use an angled bracket 40as the first character libcurl assumes you provided a single email address and 41encloses that address within brackets for you. 42 43When performing an address verification (**VRFY** command), each recipient 44should be specified as the username or username plus domain (as per Section 453.5 of RFC 5321). 46 47When performing a mailing list expand (**EXPN** command), each recipient 48should be specified using the mailing list name, such as `Friends` or 49`London-Office`. 50 51Using this option multiple times makes the last set list override the previous 52ones. Set it to NULL to disable its use again. 53 54# DEFAULT 55 56NULL 57 58# %PROTOCOLS% 59 60# EXAMPLE 61 62~~~c 63int main(void) 64{ 65 CURL *curl = curl_easy_init(); 66 if(curl) { 67 CURLcode res; 68 struct curl_slist *list; 69 list = curl_slist_append(NULL, "root@localhost"); 70 list = curl_slist_append(list, "person@example.com"); 71 curl_easy_setopt(curl, CURLOPT_URL, "smtp://example.com/"); 72 curl_easy_setopt(curl, CURLOPT_MAIL_RCPT, list); 73 res = curl_easy_perform(curl); 74 curl_slist_free_all(list); 75 curl_easy_cleanup(curl); 76 } 77} 78~~~ 79 80# %AVAILABILITY% 81 82# RETURN VALUE 83 84Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. 85
