Some of these can also be useful for outbound mail – for example, you should detect and notify when executables are sent outbound as it could be indicative of an internal outbreak which you obviously want to know about.
Just in case you’re reading this and haven’t seen the IronPort x60 replacement programme e-mail – here goes

So by default you can create a catchall account for the primary domain but the same option is not given for secondary/additional domains.
Luckily there is an easy work around for this and we can create a catchall address for any of your Google Apps domains.
The reason I write this post is because most of the guides I found online (when I was searching for a solution for myself) did not seem to implement this in an efficient way (applying the policy to the entire Google Apps ‘company’ rather than on individual domain basis).
