 Replying to [comment:6 iandunn]:
 > What about instead of applying ''wp_filter_kses'', we pass the new
 address through PHP's
 ''[http://php.net/manual/en/filter.filters.sanitize.php
 FILTER_SANITIZE_EMAIL]''? That would strip out all characters except
 letters, digits and {{{!#$%&'*+-/=?^_`{|}~@.[]}}}

 I'm curious about this myself, and how it relates to our other is_email
 tickets.  I'm going to tag them all as related for now.
