[ale] limiting access to e-mail aliases

I wrote my own program which pipes mail sent to the alias into that 
program.  It finds the From address, and if it likes it, it'll send 
the mail on to another alias which actually does go to everyone, at 
the same time rewriting the headers so someone getting the mail won't 
be able to figure out that alias.   Kinda what majordomo allows, but 
this way I can have lots of authorized people.

Problems:  1) E-Mail addresses are easy to fake.  However, since that 
is not legal in GA, I don't have to worry about it (hahaha)
2) Anyone that has read access to /etc/aliases would be able to see 
what the true alias is and send mail to that.  In my case, I'm the 
only one that actually logs onto the machine.
