[ih] Early email systems

[ian.peter at ianpeter.com]

Hi,

Just following up on the recent discussion here on early email systems:

Does anyone know the origins of mailer Daemon notifications? I guess 
they have been around for sometime but if anyone knows when they were 
introduced I would be interested.

Also, were there any systems in email preceding this which notified eg 
when a message was not sent, when a system was offline, could not be 
delivered etc?
