Exim MTA: How do I route or relaying via a smarthost?

I never used exim. My faviorate MTA is postfix. But this time I needed to configure exim MTA (mail transfer agent used in Unix-like operating systems) to router all mails using a smarthost called mta3.somewhere.com

Open exim configuration file i.e. begin routers section and add or modify it as follows:

smarthost:
driver = manualroute
domains = *
transport = remote_smtp
route_data = "mta3.somewhere.com"

Restart exim to take effect.

the domains should be domains = ! +local_domains otherwise mail for the local machine could be sent out to the smarthost then back.

Dear friends,

I am new with EXIM.
Do you know how to configure EXIM to route mails to another SMTP address for specific domain destination?
Example:
The primary EXIM domain is @abc.com,
The EXIM should route all mails to host server01.abc.com that email destination’s domain with @server01.abc.com
Do you know how to accomplish it with EXIM?
note: the domain @server01.abc.com is not registered in DNS

Thank you very much
