# Changelog for chatmail deployment 

## untagged

- Migrate and remove sqlite database in favor of password/lastlogin tracking 
  in a user's maildir.  This removes the need for "passdb" setting in ini file
  which was introduced through #351 below. 
  ([#379](https://github.com/deltachat/chatmail/pull/379))

- BREAKING: new required chatmail.ini values:

  mailboxes_dir = /home/vmail/mail/{mail_domain}
  passdb = /home/vmail/passdb.sqlite
  
  reducing hardcoding these two paths all over the files, also improving testability. 
  ([#351](https://github.com/deltachat/chatmail/pull/351))

- BREAKING: new required chatmail.ini value 'delete_inactive_users_after = 100'
  which removes users from database and mails after 100 days without any login. 
  ([#350](https://github.com/deltachat/chatmail/pull/350))

- Refine DNS checking to distinguish between "required" and "recommended" settings 
  ([#372](https://github.com/deltachat/chatmail/pull/372))

- reload nginx in the acmetool cronjob
  ([#360](https://github.com/deltachat/chatmail/pull/360))

- 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. 
  If it's an issue, a chatmail operator can still care to properly set reverse DNS. 
  ([#348](https://github.com/deltachat/chatmail/pull/348))

- Make DNS-checking faster and more interactive, run it fully during "cmdeploy run",
  also introducing a generic mechanism for rapid remote ssh-based python function execution. 
  ([#346](https://github.com/deltachat/chatmail/pull/346))

- Don't fix file owner ship of /home/vmail 
  ([#345](https://github.com/deltachat/chatmail/pull/345))

  ([#323](https://github.com/deltachat/chatmail/pull/323),
   [#324](https://github.com/deltachat/chatmail/pull/324))

- improve filtermail checks for encrypted messages and drop support for unencrypted MDNs
  ([#320](https://github.com/deltachat/chatmail/pull/320))

- replace `bash` with `/bin/sh`
  ([#334](https://github.com/deltachat/chatmail/pull/334))

  ([#335](https://github.com/deltachat/chatmail/pull/335))
