There will be many ways to do this, depending on your exact requirements. For
example, you could have a second lookup file which names the accounts which
are restricted:
# in /etc/exim/restricted-aliases :
all
example
then have an ACL which disallows non-local access to those accounts:
deny
domains = example.com
local_parts = /etc/exim/restricted-aliases
hosts = !+local_hosts
message = Some message here ...
where the +local_hosts hostlist defines which hosts are allowed to address the
restricted accounts.
On the other hand, if you want more flexibility (multiple domains, multiple
definitions of who can bypass the restriction, etc), that'll almost certainly
be possible too, as long as you can define what it is exactly that you want.
