Email inside cron

[Bob Smith]

Ooops, my bad.  I'm so embarassed!  I had this in a working script doing
exactly what was requested, and didn't look too closely.

Currently, when cron runs, the environment is very limited.  Here's an
example of what is set under the root user:

SHELL=
PATH=
_=
PWD=
HOME=
SHLVL=
LOGNAME=

When run under cron as a different user, at least on my system, the env
variable names are the same, although the user specific values are
different.  However, the environment that you have under normal operation
is very much larger, and includes aliases.  So you might check to see what
environment variables your version of mail uses, or what your version of
mail is aliased to.
