CURLOPT_MAIL_FROM(3)       curl_easy_setopt options       CURLOPT_MAIL_FROM(3)

NAME
       CURLOPT_MAIL_FROM - SMTP sender address

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAIL_FROM, char *from);

DESCRIPTION
       Pass a pointer to a null-terminated string as parameter. This should be
       used to specify the sender's email address when sending SMTP mail with
       libcurl.

       An originator email address should be specified with angled brackets
       (<>) around it, which if not specified will be added automatically.

       If this parameter is not specified then an empty address will be sent
       to the mail server which may cause the email to be rejected.

       The application does not have to keep the string around after setting
       this option.

DEFAULT
       blank

PROTOCOLS
