 In wp-includes/pluggable.php, lines 324-332, wp_mail() handles the case
 where no From: header is provided to an email, by attempting to create one
 (wordpress at domain).

 The domain is determined by looking at `$_SERVER['SERVER_NAME']`, which
 fails when wp_mail is called outside of the context of a Web server (i.e.
 if called from a wp-cli script).

 Using something like `substr( home_url( '', 'http'),7)` might be a
 suitable substitute when $_SERVER is unavailable. (If there's a better way
 to get a site's hostname than slicing up home_url() that of course would
 work too.)
