I run a Linux server running RedHat 9.0. I've always just ignored this issue because it really didn't affect myself or the couple two or three users until now. I am running IMAP and POP for users who want it however, it's a bit of a pain for them to search the whole server for the files they subscribe to because they are not Jailed to their home dir.

I have enabled Jailing with FTPD but not done jail shell. I haven't been able to figure out much about this topic online however, I'm looking for advice.

Specifically, do I need to be using Jail Shell to restrict IMAP to the home dir, if so, how do I install jail shell. If not, what do I need to do?
