+# NAME
+
+CURLOPT_MAIL_FROM - SMTP sender address
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAIL_FROM, char *from);
+~~~
+
+# DESCRIPTION
+
+Pass a pointer to a null-terminated string as parameter. This should be used
+to specify the sender's 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.
+
+In order to specify DSN parameters (as per RFC 3461), the address has to be
+written in angled brackets, followed by the parameters.
+
+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.
+
+# DEFAULT
+
+blank
+
+# %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_FROM, "president@example.com");
+    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).
