I don't understand how to prevent / resolve the following error from
occurring when removing the ban:
2019-01-20 18:25:41,748 fail2ban.actions [16393]: NOTICE
[postfix-sasl] Unban 185.234.218.35
2019-01-20 18:25:41,962 fail2ban.action [16393]: ERROR

185.234.218.35 --unban -- stdout: b''
2019-01-20 18:25:41,962 fail2ban.action [16393]: ERROR

/etc/fail2ban/fail2ban-pgsql.php postfix-sasl tcp smtp
185.234.218.35 --unban -- stderr: b'iptables: No chain/target/match
by that name.\n'
However The unban does execute successfully. I believe the file
triggering the ban is
/action.d/iptables-multiport.conf
The unban within this file is
actionunban = iptables -D f2b-<name> -s <ip> -j <blocktype>
I am new to this. I could be mistaken that this is this is the
source. That is where I've tracked it back to.
I appreciate any help.
Ron
