CURLOPT_MAIL_AUTH(3)       Library Functions Manual       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
       environment 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.

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


DEFAULT

       NULL


PROTOCOLS

           curl_easy_setopt(curl, CURLOPT_URL, "smtp://example.com/");
           curl_easy_setopt(curl, CURLOPT_MAIL_AUTH, "<secret@cave>");
           res = curl_easy_perform(curl);
           curl_easy_cleanup(curl);
         }
       }
