I have started getting error messages from *.AC.UK" from the list I
run on ua1vm ([log in to unmask]).  The error message is:
 
------------------------------------------------------------------------
ua1vm.ua.edu unable to deliver following mail to receipient(s):
      <[log in to unmask]>
      <[log in to unmask]>
      <[log in to unmask]>
      <[log in to unmask]>
      <[log in to unmask]>
      <[log in to unmask]>
 
      (several other addresses)
 
ua1vm.ua.edu received negative reply:
501 Unknown domain 'UA1VM.UA.EDU"
------------------------------------------------------------------------
 
I have had no problem before with the above addresses and right now I only
have 9 rdr files showing this error.  Is this a problem with my side of the
world or theirs?
 
Thanks.....
