If anyone knows of an email server I can use until I get a break, can find and read my Linux books on setting up an old Pentium Celeron box that at the moment has Microsoft's shit on it with a mail server, or can pick a Linux server up, that allows me to bottom-post it would be a big help.
If you want an external server, then fastmail.fm has free IMAP accounts (or did, and may have cheap ones, now), and some countries Yahoo.com has free POP3.
If you want to run your own server, then you can use any mail service that lets you access it with something like POP or IMAP. You'd use something like fetchmail to drag mail from an external mail server, and use your own local mail server running on your computer.
That's just two approaches.
If you're happy with usenet (news groups), you can access this list through the gmane news group server.
