* first adjustments to use Fail2Ban with nftables * replace `iptables` -> `nftables` and adjust tests nftables lists IPs a bit differently , so the order was adjusted for the tests to be more flexible. * line correction in mailserver.env * change from `.conf` -> `.local` and remove redundant config * revert HEREDOC to `echo` Co-authored-by: Casper <casperklein@users.noreply.github.com>
