CURLOPT_MAIL_FROM(3) Introduction to Library Functions 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 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
