Comment (by mensmaximus):

 To make the function more flexible and to strip the subdomain for email
 addresses we could pass some arguments:

 {{{
 #!php
 function get_current_domain( $strip_subdomain = true, $blog_id = '' ) {
         $blog_id = empty( $blog_id ) ? get_current_blog_id() : $blog_id;
         $domain = parse_url( get_home_url( $blog_id ), PHP_URL_HOST );
         if ( true === $strip_subdomain ) {
                 $domain_parts = explode ( ".", $domain );
                 array_shift( $domain_parts );
                 $domain = implode( '.', $domain_parts );
         }
         return $domain;
 }
 }}}
