This is a terrific list to work up. Of course it changes over time.... 2003-01-30T11:47:21 Marcus J. Ranum:
tn-gw ssh
For a gateway, I've constructed a highly restrictive ssh proxy setup. It used a chrooted sshd with private passwd/shadow files in the chroot jail. The login shell for the users in that private passwd was a teensy C program, that looked up the $LOGNAME in a private config file to get a destination host, and execed an ssh client to that host. This prevented all port forwardings and the like. This was work-for-hire, and I no longer have that code and couldn't give it away if I did, but such a C wrapper is awfully trivial to write.
smap postfix
While I like Postfix best for such applications, another candidate I wouldn't criticize is qmail. Different strengths and weaknesses, appeals to some folks.
dns bind, chrooted (finally)
djbdns --- dnscache is deal for use as a firewall DNS proxy. -Bennett
