I installed fail2ban on centos 7, configured a jail for sshd, tested it, and
it's working just fine, banning my ip address.
Postfix is also working just fine on the machine, I tested it using this
command, and I can receive the email. echo "body" | mailx -s "subject"
[email protected]
My problem is that it does not send an email out, when an ip address is banned.
In /etc/fail2ban/jail.local I tried configuring mta=sendmail, mta=mail and
mta=mailx but it doesn't sent email when banning an IP.
Since I know postfix is able to send out emails, how can I configure fail2ban
to use postfix to send out emails?
Thanks
