12.05 update causing exim syntax errors

[cloudseeder]

After the 12.05 update my lfd log is full of exim syntax errors:

Aug 10 08:17:20 vpc5 lfd[2111376]: Exim syntax errors from

resulting in my ingress mail servers to be blocked.

I see this in the changelog:

Added new regex for LF_EXIMSYNTAX


I whitelisted my ingress servers to get mail flowing again but any help to fix the issue would be appreciated.

Upgrade to 12.06. We reverted the change due to the chance of false-positives for mail servers without correct DNS lookups.

Found it. This must be a new rule:

if (($config{LF_EXIMSYNTAX}) and ($globlogs{SMTPAUTH_LOG}{$lgfile}) and ($line =~ /^\S+\s+\S+\s+(\[\d+\] )?no host name found for IP address (\S+)/)) {

My ingress mail servers are running on AWS and connect to the servers running CSF/LFD using private IP addresses without in-addr (intentional) mapping.

What should we do to correctly fix this issue?

As you've already been told, this issue was fixed in the latest version, so you should upgrade.
