Dear all,

      Please give me some comments about this case. I always got some
messages which sender's SMTP address shows that mail account on my
commany's Exchange server, but actually it does not on our mail server at
all. that mail address is not exist on my server.
      They can send this mail by using some 3rd software which needn't
check name. How can I do to prevent this happen again?

Thank you so  much for you help!

Best Regards,
