I'm interested in finding out for central and local government entities what buckets email falls into. So, for a typical month:
- How much email is entirely within the domain (so never leaves the department or local authority servers)?
- How much email is to other equivalent bodies (so in central government to or from the GSI or similar networks)?
- How much email is to or from the Internet
I thought this might give an interesting view on the likely levels of security needed in cloud email. It won't say everything but it might help.
So if you have that kind of info - or want to speculate - let me know. All data gratefully received, even anonymously.
