NAME

       CURLOPT_SASL_IR - send initial response in first packet

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SASL_IR, long enable);

DESCRIPTION

       Pass  a  long. If the value is 1, curl will send the initial response to the server in the
       first authentication packet in order to reduce the number  of  ping  pong  requests.  Only
       applicable to the following supporting SASL authentication mechanisms:

       * Login * Plain * GSSAPI * NTLM * OAuth 2.0

       Note:  Whilst  IMAP supports this option there is no need to explicitly set it, as libcurl
       can determine the feature itself when the server supports the SASL-IR CAPABILITY.

DEFAULT

       0

PROTOCOLS

       IMAP, POP3 and SMTP

EXAMPLE

       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "smtp://example.com/");
         curl_easy_setopt(curl, CURLOPT_SASL_IR, 1L);
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }
