This is a very small, fast scanner which operates over class B networks and a
perl script which uses it to scan for open e-mail relays.  Version 1.8 works
on Linux 2.0.35 and later and Linux 2.2.8 and later.

Also here is RH5.0-5.2-patchscript - a script to fix a problem in RedHat 5.0
to 5.2's relaying rulesets where certain envelope recipients could be used to
trick the anti-relaying rulesets.
