Modifying the envelope information

[Scott C. Villinski]

I've got SA running with Postfix and it's working just fine.  However, I 
wanted to modify spamd so that any detected SPAM would be routed to a 
different user.  How can I go about modifying the envelope information? 
 Right now I'm able to modify the headers, but Postfix still routes the 
message onto the original recipient.

Thanks!
Scott
