I'd like fail2ban to send me alert emails for any events. There seem to be dest variables littered throughout the config files in /etc/fail2ban and /etc/fail2ban/action.dIs there a way to set one destination email for all events? I can't seem to find up to date documentation on this.jail.local contains:# ban & send an e-mail with whois report to the destemail.action_mw = %(banaction)s[name=%(__name__)s, bantime=%(bantime)s, port=%(port)s, protocol=%(protocol)s, chain=%(chain)s]            %(mta)s-whois[name=%(__name__)s, dest=%(destemail)s, protocol=%(protocol)s, chain=%(chain)s]But where is destemail set? It would also be useful to know how to quickly test that the destemail is working.
