I was just reading "TCP/IP Illustrated" and found that one of the ways to find all sources of RFCs is to send the following email:
To: rfc-info@ISI.EDU
Subject: getting rfcs
help: ways_to_get_rfcs
Tried it for fun -- how could I not when it's such a interesting/intriguing way of getting info? I mean, would you even think of sending an email to some remote address to get the ways to get rfcs? -- and got "Delivery to the following recipient failed permanently". I'm pretty sure it's long dead, but do you know when?
