here's a demo module that should set a drupal message when either the 'send' or the 'user_edit' forms are submitted:

<?php

function sendtest_form_alter($form_id, &$form) {
  if ( $form_id == 'send' || $form_id == 'user_edit' ) {
    // msg appears on both user_edit AND on send form
    drupal_set_message('sendtest_form_alter() called');
    $form['#submit']['sendtest_process_send_form'] = array();

    // can overwrite #submit and it works fine with send, but of course send processing
    // is never done
    //$form['#submit'] = array('sendtest_process_send_form' => array());
  }
}

function sendtest_process_send_form($form_id, &$form_values) {
  // works on user_edit but NOT on send form
  drupal_set_message('sendtest post submit function called');
  return;
}

?>

This module works as expected if the user_edit form is submitted (message appears). But it does not work with the send form (send to a friend node form).

The issue you are having is the result of send's drupal_goto after it processes the form, which means it never gets to your submit callback. This happens on a variety of modules (e.g. webform).

There may be a better fix, but for now my reccomendation is to replace the following line:

$form['#submit']['sendtest_process_send_form'] = array();

With this one:

$form['#submit'] = array('sendtest_process_send_form' => array()) + $form['#submit'];

This will prepend your callback onto the #submit array, which will ensure that your code gets called before send does any sort of goto magic.
