I prefer to have both positive and negative messages.  Positive 
indicates that things did run, correctly.  Negative indicates that there 
was a problem.

I typically like to have the emails have a key word / phrase / message 
that I can tune mail filters to.  Everything gets filed in a folder. 
Positive messages are marked as read.  Negative messages are NOT marked 
as read and may have the priority raised.

That way I can see when there is a message that needs my attention -and- 
I have all the positive messages that I've been ignoring telling me that 
things are working as they should, when I go look.

I detest when things silently stop being executed.  Thus why I like 
occasionally (when I think about it) looking to see and mentally say 
"Yep, it's still running, correctly at that.".

I think it's a data display / presentation issue.  IMHO having the data 
is always good.  Choosing what to display, by default, is extremely 

In my above scenario, I can create an additional script that will check 
to see if there are new messages (in the Maildir) for the system, and 
let me know if it hasn't seen something in the last x number of days.
