I'll start to see that SERVFAIL message in /var/log/named/bind.log on my machines, and it seems to be placed in /var/log/messages on yours.
How you'd be getting that on PTR lookups is odd though. Could you maybe post the full named.conf and list any authoritative zones that you have?
I've checked named.conf and I have got my zone files in the correct place. I'll try and post my named.conf file later today.
Note that all the IP's in the log in the original post are not mine, they are mostly from e-mails going through my server. I suspect that Postfix and blacklisted IP's via spamhaus.org have something to do with the errors.
