You don't say which version of IMP you are using, but I use the following 
hook in IMP 3 to make sure all usernames are lowercase:

$conf['hooks']['vinfo'] = 'imp_get_vinfo';

if (!function_exists('imp_get_vinfo')) {
         function imp_get_vinfo ($type = 'username') {
                 if ($type == 'username') {
                         return strtolower($_SESSION['imp']['user']);
                 } else {
                         return new PEAR_Error('invalid type: ' . $type);
                 }
         }
}


You can easily use the vinfo hook to do what you want.  Just replace the 
line above:

         return strtolower($_SESSION['imp']['user']);

with:

         return 'm-cam/' . strtolower($_SESSION['imp']['user']) . '/ag';


(I included the strtolower so that users don't get different prefs when 
they vary the case of their login name)
