The https://drupal.org/project/google_cse module appears to be a dead project - the Drupal 7 port hasn't had any activity in over 2 years.

In January 2010 I attended a launch party for Drupal 7, and was real excited at the new features etc. But I started to look into upgrading my sites, and found a bunch of modules had not been ported to Drupal 7 yet.

One of the things Drupal does is generate emails for a variety of reasons. For example new account registrations include a step to validate the account, by sending an email containing a validation link.

I've been hosting my Drupal sites on Dreamhost for quite awhile, but it's time to move on.
