- other small stuff
Modifications are go
--------------------
This is not the original Mail-in-a-Box. See https://github.com/mail-in-a-box/mailinabox for the real deal! Many thanks to [@JoshData](https://github.com/JoshData) and other [contributors](https://github.com/mail-in-a-box/mailinabox/graphs/contributors).
I made a number of modifications to the original Mail-in-a-Box, some to fix bugs, some to ease maintenance for my personal installation, to learn and to add functionality.
Functionality changes and additions
* Change installation target to Ubuntu 20.04. Thanks to [Power Mail-in-a-Box](https://github.com/ddavness/power-mailinabox)
* Add geoipblocking on the admin web console
This applies geoip filtering on acces to the admin panel of the box. Order of filtering: block continents that are not allowed, block countries that are not allowed, allow countries that are allowed (overriding continent filtering). Edit /etc/nginx/conf.d/10-geoblock.conf to configure.
* Add geoipblocking for ssh access
This applies geoip filtering for access to the ssh server. Edit /etc/geoiplookup.conf. All countries defined in this file are allowed. Works for alternate ssh ports.
* Make fail2ban a more strict
enable postfix filters, lengthen bantime and findtime
* Add fail2ban jails for both above mentioned geoipblocking filters
* Add fail2ban filters for web scanners and badbots
* Add solr full text searching to dovecot
* Add rkhunter and chkrootkit
* Configure domain names for which only www will be hosted. Edit /etc/miabwwwdomains.conf to configure.
* Add some munin plugins
* Update nextcloud to 20.0.8
* Update roundcube carddav plugin to 4.1.1
Bug fixes
* Munin routes are ignored for Multi Factor Authentication [see github issue](https://github.com/mail-in-a-box/mailinabox/issues/1865)
* Munin error report fixed [see github issue](https://github.com/mail-in-a-box/mailinabox/issues/1555)
* Correct nextcloud carddav url [see github issue](https://github.com/mail-in-a-box/mailinabox/issues/1918)
Maintenance (personal)
* Automatically clean spam and trash folders after 120 days
* Removed Z-Push
* After a backup, restarting of services is moved to before the execution of the after-backup script. This enables mail delivery while the after-backup script runs.
* Add weekly pflogsumm log analysis
* Enable mail delivery to root, forwarded to administrator
* Remove nextcloud skeleton to save disk space
Fun
* Add option to define ADMIN_IP_ADDRESS (currently only used to ignore fail2ban jails)
