Comment (by jrfoell):

 Just adding a note here so this doesn't get forgotten, since it appears to
 be 4 years old :-/

 I was able to get around the problem during a bulk user import (where the
 dataset is known) by doing:

 {{{#!php
 <?php

 if ( strpos( $user_email, '&' ) !== false ) {
         //Turn off wp_filter_kses for this email
         remove_filter( 'pre_user_email', 'wp_filter_kses' );
 }

 wp_insert_user(...);

 add_filter( 'pre_user_email', 'wp_filter_kses' );
 }}}

 I wouldn't advise doing this to open user registrations... posting here to
 help this issue bubble up :)
