Since Matthew Crocker has seen fit to insult my earlier advice (I think the
advice to stay as far away from Linux as you possibly can is quite valuable)
here's some free help that will work on Linux (and Unix, free or otherwise).
Get 'tpage', It's a free source code package written in C and Perl, and
provides an alphanumeric paging queue that can act as a mail filter, sending
the subject, author and as much of the body as your paging system allows.
ftp://ftp.cso.uiuc.edu/pub/security/coast/unix/tpage/
I've been using it for various projects on numerous OS's since '92 with
very good results. It may take some tweaking to talk to your local paging
company- some are more flexible than others.
(P.S. Hey Matt, when did you become such a grouch?)
