It's on topic, so there's no call to ask for the discussion to be discontinued here. The facts are pretty simple: 1) When *sending* email, mutt uses the file's extension to decide which MIME type label to give the attached file. 2) When *receiving* email, mutt will use the sender's MIME type label to decide how to deal with the attachment. 3) Many other programs besides mutt will also use file extensions to determine how to deal with input files. 4) File extensions are used by programs on every operating system. This has been the case since before MS-DOS existed; it continues to this day; and it will continue for the foreseeable future. 5) Kernels don't know or care about filename extensions. However, confusing a kernel with a whole operating system is a mistake. Programs such as file managers are part of the operating system, and file managers almost always care about file extensions.
