If the filename was like somefile.jpeg.exe it should have been blocked anyway
by default banned File name for having a .exe final extension. The file you
have however is of the form somefile.jpeg.exe.zip Which is a different file. If
it is actually a zip file it should get unzipped and checked for an exe
assuming you Have an unzipper. (Check what Amavisd reports as it starts up).
I have left the banned_file checks as default (other than actually turning them
on) and it works fine.
Kind regards
Benedict White
