Er, well... that is entirely *policy*, not technology:-).
Depending on your setup and "local rules"... you assumptions might not
hold true Dennis.

And then there is the argument that a notification might be as
irritating as any spam... Exactly as you go on...:-).

Well, for certain setups (at least!) they would _never_ really just
disappear... They would end up in quarantine ad/or logged as
stripped... Possibly combined with a quarantine report.
So again, that would all depend:-).

Sounds like a nice setup, probably fitting your policy well;-).
Mine looks quite different (I wont bore you with the details...
again:-), and fit my requirements/policy equally well... Without
almost any notifications at all.
