Firstly, that’s not specifically an Exim problem - you probably need to be asking the question on a WHM mailing list as that’s what you’re using. > Read attached exim error log file and the current iptable > configuration for details. Notwithstanding the above, you don’t appear to have a generic: -A [chain] -i lo -j ACCEPT rule at the top of your file. That would solve your problem, and any others you might have whereby the machine wants to talk IP to itself - it will *always* talk to itself on interface lo, rather than the ethernet interfaces, because that’s the shortest and least interruptive path.
