Only the weakest email clients do threading via the subject line: it's far too arbitrary and error-prone :-). If your mail client has an option to view all headers, or view the message source unfiltered (I know things like Microsoft Outlook cannot do this) you should take a look sometime. There are LOTS of very interesting headers in a typical email message. One of them is a Message-ID: header which contains a globally unique string which identifies this email from all others. Another is a References: header, which contains a list of Message-ID values that your message is replying to. Whenever you reply, the new message you created contains in a References: header which is a copy of the References header from the message you're replying to, plus the message-ID of the message you're replying to, so it grows as threads are created. This is how all right-thinking email clients construct threads. Cheers! -- ------------------------------------------------------------------------------- Paul D.
