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..... -- jf
