Redirecting a file works, but how would I go about cat'ing or echo'ing an 
environment variable?

I tried:
export MSG="Some Message"
mail -s "Mail Test" tim at thewunders.org < /bin/echo $MSG

And I get the contents of the file /bin/echo :-(

I also tried 
mail -s "Mail Test" tim at thewunders.org < $MSG

And bash tells me "$MSG: ambiguous redirect"

Oh well, back to Roger's way and using sendmail, I guess...
