This happens to everyone; it's not a problem. qmail will try to send bounces,
which will bounce if the envelope sender is invalid. Then you, as postmaster,
delete the double-bounces.

qmail-smtpd (the process actually accepting the mail over the network) doesn't
know anything about users; it only knows what domains are valid on your
server; therefore anything in those domains is accepted. There are patches to
change this if you like, but I don't use them.
