Here is an example vinfo hook that we use to force all usernames to 
lowercase:

if (!function_exists('_imp_hook_vinfo')) {
         function _imp_hook_vinfo($type = 'username') {
                 if ($type == 'username') {
                         return preg_replace('/\s/', '', strtolower($_SESSION['imp']['user']));
                 } elseif ($type == 'vdomain') {
                         return '';
                 } else {
                         return PEAR::raiseError('invalid type: ' . $type);
                 }
         }
}


You could replace the code inside "if ($type == 'username') { ... }" with 
code to convert from "info at adomain.com" to "a1".  Perhaps you have this 
mapping stored in LDAP, MySQL, or a flat file?  The specifics would be up 
to you.
