If the recipient is on your system, then it is possible. However, if the 
recipient is remote, and the sender chooses to use a remote SMTP server to 
send email, then it's not possible in either Exim or Exchange.

You could (probably should) prevent local users accessing remote machines 
on port 25. You should also provide SMTP access (authenticated only) in 
port 587, so that your users can reach your server, wherever they are.

You might consider publishing strict SPF records to prevent staff using 
third party SMTP servers. They could fall foul of forwarding problems, 
though. And, this will only work where the recipient's mail server respects 
the SPF record.

You still can't be sure that your staff will always send email through your 
servers, though.

Yes, you can keep a copy of emails that pass through your system. The 
easiest way would be to add a local Bcc recipient to every email, probably 
in a system filter file.

In the UK, it's probably a legal requirement to inform all your local users 
that you do this.
