 - BREAKING: new required chatmail.ini value 'delete_inactive_users_after = 25'
   which removes users from database and mails after 25 days without any login. 
+  ([#350](https://github.com/deltachat/chatmail/pull/350))
 
 - remove checking of reverse-DNS PTR records.  Chatmail-servers don't
   depend on it and even in the wider e-mail system it's not common anymore.
