While we have your attention, can you comment on the requirement of
Spam Bouncer to use ksh? I don't see anything Bourne-unfriendly in
there, but I haven't looked very closely at the code, and somebody on
the list stated it would not work with /bin/sh (unless I'm mistaken
and he was talking about csh or tcsh [yech]). This is one of the
recurring questions about Spam Bouncer and a rather serious
restriction to its usefulness -- ksh is by no means as widespread as
some people would like to make believe.
But there's always pdksh, available from ftp.cs.mun.ca/pub. Even though
it's not a 100% compatible Korn shell, it should be close enough.
