[cobalt-developers] Preventing spam relaying on Qube3



Hi there all

I am running a Qube3 and I have a have been notified that there are people
relaying spam off me.

How do I set up an RDNS entry/entries to help prevent that, as well as
whatever other effective methods of preventing spammers relaying off the
Qube?

Regards,
