I don't THINK that'll work (not at home as I write this):  the logs
show

sendmail: gethostbyaddr(192.168.xxx.yyy) failed

So as far as I can tell, the look-up is the reverse of a domain name
look-up, it's trying to find what the domain name for the IP address
is. 

At least that's what it looks like to me.  I'm not at all an expert on
either sendmail or DNS!
