NEW attachment error on incoming mail

ATTACHMENTS SCRAMBLED ISSUE HERE!!   An email just came in with an attached XLS file - and the usual embedded company logo in sender’s email signature.

In this mail, the logo is NOT DISPLAYING. ( just an empty box with the filename displayed within - filename less the extension)

And when I download the attachment, it comes down as data file of THE LOGO (25kb), but with the filename of the XLS attachment. The actual (1.5mb) XLS attachment is nowhere to be found!

Opening the mail in webmail client it all works perfectly.
