Of course they do.... the comment from the default config that you
pasted tells you what happens - Exim tries to route the address... in
other words, it runs the address through its router config to see if
the address would 'work' if a message were to be sent there. It stops
after the routihg phase, no transports are called - so no attempt is
actually made to deliver a message.

You have to specifically configure the callout functionality. The docs
are a good resource here...
