Zitat von Edwardo Garcia <wdgar...@gmail.com>:
Is possible with dovecot? Legal department have told us we need to stop anyone from delete email on corporate mail server, so nobody, even managers can not anymore delete any mail?
You want to use something like e.g. Mailpiler for that task (http://www.mailpiler.org/en/index.html), Mailstore (http://www.mailstore.com/) or Benno (http://www.openbenno.org/).
This is the stuff your legal departmant is looking for.
