That shouldn't be the case. As I said, these messages are being forwarded by a 'cc' instruction in the user's .mailfilter file on the first server. Besides, the server uses maildirs, not mbox files. > The message headers also show an intermediate Received: header from some > gizmoware called "SAVSMTP".

At this point, that is simply being used as a outbound mail relay and has been in place for years and has not been touched in quite a while. And since it's header comes above the blank line in the headers, I wouldn't expect it to be related. However, it does seem to be involved. If I bypass the Symantec relay, the problem does not occur. When sending directly to the other Courier server, the From line is silently removed from my test case. I will probably be removing that relay since it is there for historical reasons and is not really needed now. I was trying to diagnose exactly what is happening by watching the communication between the servers, but I can't seem to turn off TLS when talking to the other Courier server. There used to be a /SECURITY=NONE switch in esmtproutes, but I don't see it in the man page now and it doesn't seem to do anything. Was this removed? How can I disable TLS between these servers so I can see the data stream? -- Bowie ------------------------------------------------------------------------------ Want excitement?
