Anonymous mail servers?

[analyst@netcom.com (Benjamin McLemore)]

Are there any anonymous mail<-->ftp servers around? I am thinking
specifically about people getting pgp and other (soon to be
contraband?) cypherpunks tools. It would be nice if there were a
server for at least these items. I suppose you would send an
appropriately composed message with a body consisting of the request
and an anonymous return address preceded by the anonymous address of
the server.

Has this already been done? Blacknet, if it exists, works like this
doesn't it? Where are the BlackNet access instructions?
