Hi - During testing I've managed to get my external client IP banned from connecting to iRedMail SMTP daemon, I can connect to the mail server from other internet ip addresses OK, just not one particular address.  I've checked the blacklists but do not see the address listed - where else do I check?

Re: SMTP Client IP Denied

Check iptables firewall rules with command:

iptables -L -n

You can unban it with "fail2ban-client" command:

*) First check "iptables -L -n" output to figure out the IP is banned in which Fail2ban jail.
*) Get the real jail name with command:

fail2ban-client status

*) Unban it with Fail2ban:

fail2ban-client set <jail> unbanip <ip>
