<br>
<br>If you do a re-send in Outlook it seems to resend the *exact* message,
<br>including Message-ID. The "fix" for this is to use M$-Exchange 2000 SP1
<br>or later; their MTA (on the server) rewrites the Message-ID of the
<br>submitted message to a unique value.
<br>
<br>Someone told me there is an issue with re-using Message-IDs in the DSN
<br>functionality too, but I've never seen that one.
