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 are added automatically.

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

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

       Using this option multiple times makes the last set string override the previous ones. Set
       it to NULL to disable its use again.

DEFAULT

       blank

PROTOCOLS
