I started looking at your (previous) patch at end of last week, and 
should be able to do some more on it this week (next week is the Exim 
course). I was torn between using a new option smtp_code, as you did, 
and allowing the user to put codes at the start of the message. That is, 
the choice between:

  message = your message here
  smtp_code = 599
  
and

  message = 599 your message here
  
The point I want to think about is extended status codes, which some 
people want. If you want something like

  message = 599 1.2.3 your message here
  
then the whole "code" is a string rather than a number, and there seems 
little point in having two different strings - why not just use one. 
(And even when there is no extended status, it has to end up as a 
string, after all.)    

I now need to look at your router code and see whether this adds 
anything to the background. Then I'll make a decision...
