This has nothing to do with the To: header. Somehow you get the mail
through SMTP (external senders?) - Then only the envelope receiver is
used.
About qmail-smtpd:
Envelope recipient addresses without @ signs are
always allowed through.
To avoid this you would have to patch qmail-smtpd.
I doubt that the sender is really external - you wouldn't get the mail
through SMTP because of missing MX records. I think there is a wild
running script or a buggy SMTP client inside your network.
