Another Fetchmail Problem

["Thomas H. George,,," <georgeacct@spininternet.com>]

fetchmail returns:

          POP3 connection to spininternet.com failed: name is valid but 
has no IP address.
          Query status = 2 (SOCKET)

With the identical account information Mozilla retrieves the mail with 
no difficulty.  I am trying to use fetchmail instead of Mozilla  because 
I would like to thread the mail I receive from the debian-user list.
