I hope someone can help me, MailScanner is stopping jpg files because 
filetype found a program in the file

May 18 08:05:44  MailScanner[26740]: Saved infected "166245Delfines.jpg" to 

I believe MS uses file to determine the type so, I execute:

# file 166245Delfines.jpg
166245Delfines.jpg: JPEG image data, JFIF standard 1.01, comment: 
"<nso="delfines.nso"> "

I do not know why MS detect an Executable in this type of file

can anyone help me

thanks in advance
