Hi All - 

I am getting a bunch of these "Data Format Errors" in my sendmail log files.  These are happening mostly when spam gets sent to a user that does not actually have a mailbox.  Below is an example of one message:

sendmail[1007]: j2PFXQgM001005: to=<aa36987 at>, delay=00:00:00, xdelay=00:00:00, mailer=cyrus, pri=512884, dsn=5.6.0, stat=Data format error

Any ideas of why I get this instead of just a stat=User Unknown?
