I disallow an unbracketed IP too. Cuts out loadsa junk.
Often as not it's *my* ip, mind, which the above would catch.
However, I also have customers (presumably behind NAT) giving
a bracketed rfc1918 address as a helo name which doesn't
match $sender_host_address, and I need to accept those. So for
now I don't compare against that.
Cheers,
