[Exim] manualroute

Hi,

I would like to use smart_host for a special domain. At the moment I use
Exim3.22.
Exim 4.x support manularoute driver, as follows:

send_to_gateway:
       driver = manualroute
       domains = special.domain.com
       transport = remote_smtp
       route_list = * relay.smtp.com

Can I solve this with Exim 3.22 somehow or I should upgrade?

Thanks,

Janos
