DDL scripts needs some updates.

ALTER TABLE `identities`
  MODIFY `signature` text NOT NULL DEFAULT '',
  MODIFY `bcc` varchar(128) NOT NULL DEFAULT '',
  MODIFY `reply-to` varchar(128) NOT NULL DEFAULT '',
  MODIFY `organization` varchar(128) NOT NULL DEFAULT '',
  MODIFY `name` varchar(128) NOT NULL,
  MODIFY `email` varchar(128) NOT NULL; 

Fixed in [d7f3d796].
