I like the filter idea with some kind of 'custodian' user that gets 
ignored by everyone :-)  The filter could be defined as a daisy query 
something like "select name where variantLastModifierName='custodian'" 

Some ideas :

* What about extending the wildcards for email notification, so that one 
might be able to specify "DSY-*, main, en" to just receive
changes on documents that belong to a certain namespace.  However 
changing the imported document on the target machine will not generate 
notifications either.

* Expose the email notifier as an MBean.  So it could be switched off & 
on by the importer, a bit how the backup locker works now.  However 
changes to 'native' documents (those that aren't being imported) will 
not trigger notifications during the import either.
