In order to use APOP, all users will need to follow these instructions. Old cs.nwu.edu users should note that the use of a separate Maildir directory is no longer necessary. Eudora and Netscape both use POP protocol to reetrieve email from the server. You need to have directory called Maildir with 3 subdirectories cur, new and tmp. If you do not have these directories use maildirmake if you already have them you can skip this step.
Secure shell is intended to work as a transparent replacement for rsh, rlogin, and rcp.
Detailed instructions on its use are available here .
