Problem with makemap and hash tables

I got that error when there was a duplicate entry.

I broke down and am now restricting emails to mailers that have a valid
forward and reverse DNS entries. Most real mailers have properly configured
DNS, but I also added a permission for those that have a DNS entry that
comes back as possibly forged.

the file /etc/mail/ForgedIP are the hosts that I will bypass the new
filter. Added to

F{ForgedIP} /etc/mail/ForgedIP

(and in the relay area)

R$+ $| $={ForgedIP}$*	$@ $1 $| $2
R$*$={ForgedNames} $| $*	$@ $1 $| $2
R$*			$: < $&{client_resolve} >
R<TEMP>			$#error $@ 4.7.1 $: "450 Access denied. Cannot resolve PTR record for " $&{client_addr}
R<FORGED>		$#error $@ 4.7.1 $: "550 Access denied. IP name possibly forged " $&{client_name}
R<FAIL>			$#error $@ 4.7.1 $: "550 Access denied. IP name lookup failed " $&{client_name}
