.TH CURLOPT_MAIL_FROM 3 "2025-06-27" libcurl
.SH NAME
CURLOPT_MAIL_FROM \- SMTP sender address
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAIL_FROM, char *from);
.fi
.SH DESCRIPTION
Pass a pointer to a null\-terminated string as parameter. This should be used
to specify the sender\(aqs 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.
.SH DEFAULT
blank
.SH PROTOCOLS
