Dear Colleques, I'm receiving errors from one of the list administrators from a list from the University Of Twente. Does anybody know what this error means? How can we prevent this error from occurring? Here is an example coming from a @hotmail.com address: Van: L-Soft list server at Universiteit Twente (1.8e) [mailto:[log in to unmask]] <mailto:[mailto:[log in to unmask]]> Verzonden: vrijdag 9 april 2004 16:23 Aan: Maarten Vissers Onderwerp: TCW2004: error report from HOTMAIL.COM The enclosed message, found in the TCW2004 mailbox and shown under the spool ID 697468 in the system log, has been identified as a possible delivery error notice for the following reason: "Sender:", "From:" or "Reply-To:" field pointing to the list has been found in mail body.
