CREATE TABLE `isp_isp_user` (
  `doc_id` bigint(20) NOT NULL auto_increment,
  `doctype_id` bigint(20) NOT NULL default '1014',
  `user_username` varchar(32) default NULL,
  `user_passwort` varchar(20) default NULL,
  `user_speicher` varchar(10) default NULL,
  `user_admin` char(1) default NULL,
  `user_shell` char(1) default NULL,
  `user_emailalias` text,
  `user_name` varchar(255) default NULL,
  `status` char(1) default NULL,
  `user_autoresponder` char(1) default NULL,
  `user_autoresponder_text` text,
  `user_mailquota` varchar(10) default NULL,
  `user_catchallemail` char(1) default '0',
  `user_mailscan` char(1) default NULL,
  `user_emailweiterleitung_local_copy` smallint(6) default NULL,
  `user_email` varchar(255) default NULL,
  `user_emailweiterleitung` text,
  `user_spamfilter` char(1) default NULL,
  `spam_strategy` varchar(255) NOT NULL default 'accept',
  `spam_hits` varchar(255) default '5.0',
  `spam_rewrite_subject` char(1) NOT NULL default '1',
