exim4 in sarge - config issues

[Hanasaki JiJi <hanasaki@hanaden.com>]

1. when did exim4 make it into sarge?

2. cool config stuff

3. smarthost configuration is working fine using the IP of the 
smarthost.  It fails when I put in the hostname of the smarthost. 
"hostname smarthost" does return the IP.  What could be wrong and how 
can it be fixed?

thanks
