"postfixadmin was updated to 3.0.2 to fix the following issues :

  - PostfixAdmin 3.0.2 :

  - SECURITY: don't allow to delete protected aliases
    (CVE-2017-5930, boo#1024211)

  - fix VacationHandler for PostgreSQL

  - AliasHandler: restrict mailbox subquery to allowed and
    specified domains to improve performance on setups with
    lots of mailboxes

  - allow switching between dovecot:* password schemes while
    still accepting passwords hashed using the previous
    dovecot:* scheme

  - FetchmailHandler: use a valid date as default for 'date'

  - fix date formatting in non-english languages when using
    PostgreSQL

  - various small fixes

  - PostfixAdmin 3.0 :

  - add sqlite backend option

  - add configurable smtp helo (CONF['smtp_client'])

  - new translation: ro (Romanian)

  - language update: tw, cs, de

  - fix escaping in gen_show_status() (could be used to DOS
    list-virtual by creating a mail address with special
    chars)

  - add CSRF protection for POST requests

  - list.tpl: base edit/editactive/delete links in list.tpl
    on $RAW_item to avoid double escaping, and fix some
    corner cases

  - fix db_quota_text() for postgresql (concat() vs. ||)

  - change default date for 'created' and 'updated' columns
    from 0000-00-00 (which causes problems with MySQL strict
    mode) to 2000-01-01

  - allow punicode even in TLDs

  - update Smarty to 3.1.29

  - add checks to login.php and cli to ensure database
    layout is up to date

  - whitelist '-1' as valid value for postfixadmin-cli

  - don't stripslashes() the password in pacrypt

  - various small bugfixes"
