Can anyone help with this.... I got a message from one of my list owners that he had received an error report as below: The enclosed message, found in the #######-L mailbox and shown under the spool ID #### 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. The subscriber who sent in the message uses cc:Mail. cc:Mail has a tendency to identify different replies within a message by use of a simple boundary..... What I am wondering is why Listserv even checks the body of the message for such content words.... or is it perhaps that there may be a problem between Listserv and cc:Mail and interpretation of these simple boundary reply separators. Perhaps Listserv is interpreting them as a separate message within the body itself... I vaguely remember that this used to be a form of annoying attack that had more to do with SendMail..... messages within messages..... Any help appreciated. Debra
