Followed the tutorial to the letter but when I get down to chapter14 Install Fail2Ban - "service fail2ban restart" Iget the following error:- output of systemctl status fail2ban.service output of journalctl -xe did a search but I couldn't find anything meaningful to me. Any Clues?
you've run `echo "ignoreregex =" >> /etc/fail2ban/filter.d/postfix-sasl.conf` too many times; you only need to add `ignoreregex =` in the [Init] section once
