problem with mailpost and inews

[Bill Tangren]

I am using mailpost to post to a local newsgroup. On my new server, this 
doesn't work. This is the error I get when I try:

inews failed: inews: warning: 502 You have no permission to talk. 
Goodbye. inews: article will be spooled

I though the problem might be that newsfeeds didn't have the proper ME 
settings, but they are the same as on the old server:

# Empty default subscription list, reject all incoming articles with a
# distribution of "local" or "collabra-internal," accept all others.
#ME:!*/!local,!collabra-internal::
ME:!collabra-internal::

Can anyone tell me what might be causing this error?
