CURLOPT_MAIL_AUTH(3) libcurl CURLOPT_MAIL_AUTH(3)
NAME
CURLOPT_MAIL_AUTH - SMTP authentication address
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAIL_AUTH, char *auth);
DESCRIPTION
Pass a pointer to a null-terminated string as parameter. This is used
to specify the authentication address (identity) of a submitted message
that is being relayed to another server.
This optional parameter allows co-operating agents in a trusted envi-
ronment to communicate the authentication of individual messages and
should only be used by the application program, using libcurl, if the
application is itself a mail server acting in such an environment. If
the application is operating as such and the AUTH address is not known
or is invalid, then an empty string should be used for this parameter.
Unlike CURLOPT_MAIL_FROM(3) and CURLOPT_MAIL_RCPT(3), the address
should not be specified within a pair of angled brackets (<>). However,
if an empty string is used then a pair of brackets are sent by libcurl
as required by RFC 2554.
The application does not have to keep the string around after setting
this option.
DEFAULT
NULL
PROTOCOLS
