+# NAME
+
+CURLOPT_MAIL_AUTH - SMTP authentication address
+
+# SYNOPSIS
+
+~~~c
+#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%
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    CURLcode res;
+    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);
+  }
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_setopt(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
