Installing DKIM

[LuKreme]

In looking for methods to install DKIM with postfix I am running into  
some old info and some new info.  It looks like the best way to handle  
DKIM is using the plugin feature of postfix and use the sendmail  
milters.

The other question is what do most people do with the check on the  
DKIM if a message fails, reject outright?  Won't this mess up any  
forwarded mail?
