Free Unix Shell, donation supported, account capability dependent on donation support level.
www.freeshell.org or sdf.lonestar.org
to create a free account, telnet (or ssh) to telnet://sdf.lonestar.org
you can set up your mail program (pine) to access mail of any other server (including gmail, and those that need SSL POP connections), and then you can forward them as attachments to Spamcop.
(forwarding with Pine: http://forum.spamcop.net/forums/index.php?showtopic=4644#)
I don't remember off the top of my head what is and isn't available as a base level, free account (actually, I think they now require a $1 token donation for a persistent account to cut down on abuse), but I think it's a fairly useful amount of stuff virtually for free. Also a good place to cut your teeth on Unix.
edit: from the site, here's what free accounts have
