            <br>

            I guess this is an issue with MailControl. If MailControl is
            rewriting<br>
            the From: with the envelope sender, they just can't handle
            this mail.<br>
            Judging from their web site, I think it's likely they are
            doing just that.<br>
            <br>
            Note that a null MAIL FROM: address is perfectly legitimate
            any time you<br>
            don't want an undeliverable DSN returned. For one example,
            almost all<br>
            MTAs send DSNs with null MAIL FROM: to avoid bounce loops.
            MailScanner<br>
            does this with user notifications for similar reasons.<br>
            <br>
            Do you have to send mail via MailControl?<br>
            <br>
            Note that the places where MailScanner sends with a null
            envelope are at<br>
