Comment (by cklosows):

 In context, this is the section I've modified:

 {{{
         if ( !isset( $from_email ) ) {
                 // Get the site domain and get rid of www.
                 $sitename = strtolower( $_SERVER['SERVER_NAME'] );
                 if ( substr( $sitename, 0, 4 ) == 'www.' ) {
                         $sitename = substr( $sitename, 4 );
                 }

                 if ( ! filter_var( $sitename, FILTER_VALIDATE_URL ) ) {
                         $sitename = preg_replace( '#^http(s)?://#', '',
 get_home_url() );
                 }

                 $from_email = 'wordpress@' . $sitename;
         }
 }}}
