Mail from mud

[Stephen Zepp <zoran#enid,com>]

Heyas...gonna ask for a little technical info here.  I would like to have my code be able to send a mail message to the
player, using a stored email address, but I'm not too sure how to go about constructing a valid message/header, etc. 
Anyone done this, or something similar?  I was thinking of somehow writing a file, then sending a command to the shell
from the mud queueing the mail for delivery, but I really am not sure how to do that..

Thanks!
