Fail2ban e-mail address keeps returning from the dead

NethServer Version: 7.5
Module: fail2ban

I keep removing this e-mail address from fail2ban, as that now auto-magically sends one to root without any configuration.

However, every time I apply any updates, it keeps coming back.

How do I permanently nuke it.

Cheers.

thank for reporting it, this is is due to this migrate fragment

github.com

NethServer/nethserver-fail2ban/blob/master/root/etc/e-smith/db/configuration/migrate/Fail2BanMail

{
    #Leave BanAction shorewall to shorewall-nethserver
    my $custom = $DB->get_prop('fail2ban','CustomDestemail')|| '';
    my $mail = $DB->get_prop('fail2ban','Mail')|| 'disabled';
    if ($mail eq 'enabled' && $custom eq '') {
        $DB->set_prop('fail2ban','CustomDestemail','admin@'.$DomainName);
    }
    '';
}

when you remove the value of admin@domain.com, this fragment restore it when you issue the event nethserver-fail2ban-update or the action /etc/e-smith/events/actions/initialize-default-databases

I will remove the fragment, then after the upgrade you could remove the CustomDestemail property
