199.183.24.247 (lists.redhat.com) is blacklisted by ORBS as an open relay. This has the following consequences: 1) Some people have trouble getting RedHat lists. 2) Spammers may potentially abuse RedHat's server. 3) It makes RedHat looks bad.
Being a former mail admin, I concur, being on ORBS is bad, very bad. I'm adding the IS department postmaster & helpdesk to the Cc: line.
IS fixed the firewalls, Alan Cox requested ORBS remove us from their system.. Out of our court...
