It checks that the sender address is "routeable". What specifically that
does, depends on your exim config. I can't see your config, so I don't know
what your routers are. However in a simple configuration, it could operate
pretty much as you suggest (it doesn't literally use "dig", but it would look
up MX records in DNS).

I can't tell that either; take a look at your /etc/resolv.conf.
