/rsh and /usr/bin/mailx - are they incompatible?

[Michael Nolan]

Thanks to several persons for the info on the PAGER variable.  I had to 
change it in the /usr/lib/mailx/mailx.rc file, but now the pager works OK.

However, now I get the following message when exiting mailx:

sh: /usr/lib/mailx/rmmail: restricted

PS:  I know that rsh is not very secure, but it's at least a little bit
more secure than sh.  Does anybody know a more secure shell?  I'm not so
much interested in defeating the bad guys, most of whom know more about unix
that I ever want to know, but in keeping amateurs (non-programmers) from doing
something that messes up somebody else's work.
