As I noted in my prior reply, notices to senders have a null envelope<br>
sender, but do contain an appropriate From: header. If there something<br>
in your MTA (Exim ?) configuration that rewrites the From: with the<br>
envelope sender address? If so, I suggest you either not do that at all<br>
or at least not if the envelope sender is not a valid email address.<br>
