What's new
I try to keep as many parts of the setup unchanged. Many of us are happy with their mail servers and want to change as little as possible. Email is a boring matter anyway and we do our jobs best if our users don’t even realize that we are there.
A few things though that are new in this version of the ISPmail guide:
- Newer software versions – it is a new Debian release after all. There are no breaking changes. Just business as usual. If you want to check the changelogs here are the version changes:
- Postfix 3.5.18 -> 3.7.6
- Dovecot 2.3.13 -> 2.3.19
- PHP 7.4 -> 8.2
- rspamd 2.7.1 -> 3.4.1
- Apache 2.4.56 -> 2.4.57
- Roundcube 1.4.13 -> 1.6.1
- MariaDB 1.21 -> 1.22
- Adminer 4.7.9 -> 4.8.1
- An improved Ansible playbook to help you automate all the steps of this guide if you want to set up multiple servers without repeating all steps manually.
- Clearer explanations. I have reworded complex parts of the configuration.
- Fixed links. The Dovecot wiki has moved around quote a lot of pages and I didn’t notice earlier because it did not lead to a 404 or a redirect.
- Dovecot now uses the “count” backend to compute a user’s quota. Previous guides still used “maildir”.
- Two chapters are currently not published: the part about Thunderbird auto-configuration because there seem to be problems with the newest versions of Thunderbird. And the part about firewalling and fail2ban because there seems to be a bug with firewalld and fail2ban. These pages deal with optional features and are not a showstopper.
