[cobalt-users] Open Relay problem

["Paul Duffield" <paul@xxxxxxxxxxxxx>]

My mail server appears to have been blacklisted for some reason unbeknown to
me.

I run a mail list on one of the domains (majordomo) AOL apparently seem to
think it has been used to spam people through open relay or some such thing.
Another ISP - freeserve has just blocked me without warning too.

Can anyone tell me how to close the open part of this relay please. cobalt

Thanks in advance,
