Eric - Yesterday we got one of those automagic updates (1.7F). We are having problems that I believe are a result. Can you explain why it might be happening or offer an alternative method of alleviating the problem? When we receive mail which has as its sender anyone with a .BITNET on the Sender: line, we receive an error indicating that the RSCS address does not match the point of origination, and the mail is not delivered. Approximately 150 messages destined for our site have not been delivered so far. They are being routed to the Postmaster instead. /++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++\ ! Later + Systems Programmer ! !
