Has anyone experienced problems with users subscribed from NHSnet addresses? I have a lot of users who are on NHSnet, and not all of them have had problems, but there are some users who have been unable to post to one of our lists, even though they are subscribed, and they are all sending from NHSnet. I've copied one of the error messages below, any ideas? -------------------------------------------------------------------------- Naomi Rousseau Internet Officer London Library & Information Development Unit (020) 7692 3390 [log in to unmask] www.londonlinks.ac.uk -------------------------------------------------------------------------- -----Original Message----- From: Mail Delivery Subsystem [mailto:[log in to unmask]] Sent: Wednesday, October 09, 2002 02:11 To: [log in to unmask] Subject: Returned mail: User unknown The original message was received at Wed, 9 Oct 2002 14:10:34 +0100 from uucp@localhost ----- The following addresses had delivery problems ----- <[log in to unmask]> (unrecoverable error) ----- Transcript of session follows ----- ... while talking to mail2.nhs.uk.: >>> RCPT To:<[log in to unmask]> <<< 550 relaying to <[log in to unmask]> prohibited by administrator 550 <[log in to unmask]>...
