Since log files are rotated and compressed, it is a lot better to avoid 
duplicating all that detail to mailboxes, where it is not compressed, 
accumulates indefinitely if not removed by user action.
(On my system log files have always been properly rotated.)

I have tended to favour installing dma, as personally I like being 
notified, but I'm beginning to think that we need another solution.

That I agree with totally.
Summaries to the mailing list (like x packages updated, y removed, z 
added), with references to log would be much better.
The defaults for the standard level are a bit ridiculous also.  How many 
users care about which applications listen on ports ?  (Which is usually 
only Internet.)

Maybe a better alternative (by default) would be to send a persistant 
alert to the screen, which refers to the log file.  And maybe has a link 
to view the detail in the log file.
The current alert disappears automatically after a few seconds, so is 
very easily missed.  (Especially since it runs at 4 in the morning, at 
least on my system.)
With a persistant alert, I wouldn't need email notification.
(I'm not running a server.)

It might be an idea for msec to store these alerts (of not more than a 
few lines each) in a special file, until each is acknowledged.  Every 
new alert appears in a window on the screen, with all unacknowledged 
previous alerts.  The window stays there until closed.  Much like a 
dedicated mailing list without headers, and very compact.  With the 
detail going to the logs.
The more I think about it, I would very much prefer this sort of default 
Just an idea :)
