If the spam filter is checking file headers, it doesn't matter if it's a txt or an exe, it will detect that it's code and will act on that (discard, quarantine, whatever). You can even check this by opening a small exe in a hex editor and looking at the first 2 bytes. A spam filter can examine the first two bytes of a file while it saves it to disk and discard it if it contains that sequence. Every PE format exe starts with the same 2 hex sequence: 4D 5A. I realize this is a really old post, but for anyone wondering why their email strips programs even after you've renamed them, here is a reply:Īctually a spam filter could easily examine a file to determine if it's a program. It could use Heuristics to check the file, but that would be done by your real-time AV engine, not the SPAM engine as the heuristics can't really be run until the package starts to get installed. When it does that, it will only see that it is an unknown file since there isn't an extension or it would see it as a text file if you change the extension to.

File headers? If we are talking about a program, the best the filter could do was to look at the properties of the file.
