It's socket to me time!

I don't know if this counts as a simple solution, but presuming you have
sockets, you can use SMTP and NNTP to yourself.  With NNTP you can likely
read news transparently.  To use SMTP, though, you'd probably have to pretend
you were another machine to get it to forward your mail.  But you can send
mail with telnet.

But you might be able to read your mail directly with FTP, depending on
how /etc/shells is set up.  Of course, if you can do that, there's little
point in the chroot in the first place...
