As a matter of fact, one would have to blame the e-mail program you use. The file extension is *not* equivalent to the file type, and the mailing list software accepts the (MIME) type text/plain and a couple of others. The problem with most modern e-mail clients/programs/apps/... is that they use something you could translate as "unknown binary format" as type for their attachments if they can't guess the correct file type from the file extension. It would be interesting to know (for me) if there are modern e-mail programs / web apps which you could *teach* about the mime type, e.g., for all files ending with extension '.R'...
Well, there's Gnus in Emacs:
(add-to-list 'mailcap-mime-extensions '(".R" . "text/x-rsrc"))
But I guess you know that ;-)
