I have had a look at the source of tcpd to try to disable reverse lookups,
but I'm in over my head.
My problem is that if a use dhcp to assign IPs to my client, when they try
to get mail diald starts up. I've figured this out to be tcpd doing a
reverse lookup and the man pages says it's a compile time option but I can't
find how to knobble it.
Unfortunately my C is a bit crap. Any help would offered would be greatfully
