CDO , Invalid attachment file name.

Dear All,

I create a CDOSession object by which I send a message with an attachment. The attachment file's name is (for example) MyFile.TXT . After I recieve the file using Outlook, the attachment has been renamed to ATT0006.DAT . if I rename this file to MyFile.TXT , it is opened well.

What should I do to solve the problem out?

Thanks
