188.8.131.52 (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...
