Hi, let me try to give you a partial answer. If you are wanting mail
alerts from some jails but not others, it's possible but I can't
reliably give you that explanation right now.
Apart from that, you should open jail.conf and then re-save it as
jail.local. All your customizations should go in fail2ban.local.
In there look for:
destemail = root@localhost
and change it to your desired email address for the notifications.
You'll need to have sendmail or postfix installed and working. sendmail
is the easiest, and is the default:
mta = sendmail
Then you need to configure the default action when a jail is triggered:
action = %(action_mwl)s
will send you an email with lines from your logs.
Beware, those email alerts arrive when you start and stop fail2ban and
every time a jail is triggered. They can become very frequent if you
have a lot of hits from bad guys, or a large number of jails activated.
HTH and good luck,
Dave

Hello,
I am able to receive these from "dovecot" banishments.
However, I would like to receive the warning for "postfix-auth" jail
malfeasance.
Which file would I have to edit to get this action. I have searched
around the places I would expect, like:
jail.conf, jail.local, fail2ban.conf but usually it says not to edit
those.
Also, checked the mail.conf and mail-whois.conf, as well as some
sendmail.conf files, but nothing stands out.
Can anyone throw me a bone? I assume it must be easy for smoeone =)
Thanks
