why would this be happening? the deliver process dies and this didn't 
start happening until I added "-e", as someone here volunteered a great 
idea, to the transport of postfix. There is an alias in postfix for this 
admin address as a catch all box for creating tickets to the right 
departments for abuse@ postmaster@ and admin at . ALL other mail delivers 
perfectly but I dont know whats with crontab on this mail server.

Thanks
