It's the mail program at the sender end that refuses to send .csv files and friends as text/plain, based on the extension. But the net result is essentially the same.

My hypothesis is that all mail clients in common use fail to label the .csv, .dat and .tsv files as text/plain if this explanation is correct. I've been watching the "behavior" of our mail-server for several years now and have not seen _any_ files with an extension other than .txt be successfully passed to subscribers. So clarifying this issue might be possible _if_ we could find a mail client for which we were certain of its labeling characteristics. Does your mail client label such files as text/plain?

It appeared to me that the authors lost their entire university-hosted website. I was unable to find another email address for sending a query to Paul Cowpertwait.
