[Mailman-Users] Problem creating list

[Kevin Carlson]

I just installed mailman on a new machine and am getting the following error
when I attempt to create a list with the newlist command:

...
Hit enter to continue with test owner notification...

Traceback (innermost last):
  File "./newlist", line 220, in ?
    main()
  File "./newlist", line 213, in main
    text)
  File "/home/mailman/Mailman/Message.py", line 211, in __init__
    OutgoingMessage.__init__(self, text)
  File "/home/mailman/Mailman/Message.py", line 205, in __init__
    self['Message-ID'] = Utils.make_msgid(idstring='Mailman')
  File "/home/mailman/Mailman/Utils.py", line 769, in make_msgid
    idhost = socket.gethostbyaddr(socket.gethostname())[0]


Any idea what is causing this?

Thanks,

Kevin
