OK, been there, done that.  Now what?

Just sent another message from the command line:

echo 'This is the message.' | mail -s 'Subject line here' at

that hasn't arrived either.

sudo nullmailer-send
Rescanning queue.
Starting delivery, 1 message(s) in queue.
Starting delivery: protocol: --port=25 host: file: 
Sending failed: Could not exec program
Delivery complete, 1 message(s) remain.

Will provide any more info required though I'm a bit outside my comfort 
zone here.
