Mail-in-a-Box can now **only** be installed on Ubuntu 18.04. +This is the first release for Ubuntu 18.04. This version and versions going forward can **only** be installed on Ubuntu 18.04; however, upgrades of existing Ubuntu 14.04 boxes to the latest version supporting Ubuntu 14.04 continue to work as normal. -When **upgrading**, you **must** upgrade your existing Ubuntu 14.04 Mail-in-a-Box box to the latest release supporting Ubuntu 14.04 --- that's v0.30 --- first. If you are running an older version of Mail-in-a-Box which has an old version of ownCloud or Nextcloud, you will *not* be able to upgrade your data because older versions of ownCloud and Nextcloud that are required to perform the upgrade *cannot* be run on Ubuntu 18.04. +When **upgrading**, you **must upgrade your existing Ubuntu 14.04 Mail-in-a-Box box** to the latest release supporting Ubuntu 14.04 --- that's v0.30 --- first.

To upgrade from Ubuntu 14.04 to Ubuntu 18.04, you **must create a fresh Ubuntu 18.04 machine** before installing this version. In-place upgrades of servers are not supported. Since Ubuntu's support for Ubuntu 14.04 has almost ended, everyone is encouraged to upgrade. + +Setup: + +* Mail-in-a-Box now targets Ubuntu 18.04 LTS, which will have support from Ubuntu through 2022. +* Some of the system packages updated in virtue of using Ubuntu 18.04 include postfix (2.11=>3.3) nsd (4.0=>4.1), nginx (1.4=>1.14), PHP (7.0=>7.2), Python (3.4=>3.6), fail2ban (0.8=>0.10), Duplicity (0.6=>0.7). +* [Unofficial Bash Strict Mode](http://redsymbol.net/articles/unofficial-bash-strict-mode/) is turned on for setup, which might catch previously uncaught issues during setup. + +Mail: + +* IMAP server-side full text search is no longer supported because we were using a custom-built `dovecot-lucene` package that we are no longer maintaining. +* Sending email is now disabled on port 25 --- you must log in to port 587 to send email. +* Greylisting may delay more emails from new senders. We were using a custom-built postgrey package previously that whitelisted sending domains in dnswl.org, but we are no longer maintaining that package. v0.30 (January 9, 2019) -----------------------
