The user may still be able, however, (depending on the mail program) to access other parts of the system (via an editor, for example). The most secure way is roll your own login "shell" (which could be a shell script) which does a "chroot" command and restricts access to only that part of a file system that you specify. This is a bit tedious to set up, however, since you have to make copies of all needed files such as the mail program, "sendmail", mailbox for incoming mail, spooling areas and on and on ... Another more modest method would be to set up a bbs program (most of them set up mail access for you). There are even decent free bbs programs (the name "eagles" comes to mind) which will set up "chroot" areas for you. _____ Larry
