Thomas,

This is actually a very old issue, but I was running a much older 
version. I was not up to date, so I did not want to raise the issue on a 
version that was that old.

I do not want to say "always". I cannot document "always". There are 
times when I see a "PTR Invalid" and that is the only error logged, even 
though there are other obvious things that should have been logged and 
counted.

In this case, the origin IP address, for which the PTR was invalid, was 
listed in a sub-net in DenyAlways. In fact, it was the very same IP 
address that earned a listing in DenyAlways.

Also, I checked the Admin Info messages. DenyAlways was clean. No issues 
listed.
