As usual, Sergey has the correct answer, but if this is something that happens very rare, what I do is have the sender rename the attachment before they send it as the filename whaterver.txt. It was real easy for me, because it was usually me sending something from work to the house. Then when I got home, I would rename it to whatever.exe, or whaterever.zip
