Hi Doug

What these look to possibly be is bounce messages? Although without
seeing a full snippet of your mailq and particularly the mail logs its
difficult to say.

If you trace these addresses in your maillogs form which hosts were they
received ? What is your domain? without all the pieces its a little
hard for people to assist you. PLease revisit the welcome message you
got when you joined the list for details on what kind of information to
provide to aid in debugging.
