Hi Joseph,
Sendmail 8.8.x is kinda stuffed in regards protection from relaying.
The easiest way to fix it is to upgrade to RH 6.1 - note that the upgrade will
probably make a complete mess trying to convert ip_allow etc into the access
file.
Also, make sure you update linuxconf to the very latest update from
RH before using it to modify sendmail (otherwise you'll be back at square 1).
