Is there nice way to get RFC doc by email?

There used to be, back when there actually existed large sections of Internet that didn't have ftp/http access. Is this really still an actual thing? If you can't just hit http://www.ietf.org/rfc/rfc793.txt with firefox or wget or something, and do a 'save as', it's probably more important to get your Internet access fixed than to find a way to get RFCs by e-mail.
