When a user sends too many messages to bad addresses, it’s probably a spammer 
using a compromised account.  Other than a very messy reading and parsing of 
the log files, is there a way to get postfix to tell me when a message has 
bounced and who the sender was (perhaps a hook in the main.cf or something??).  
 When the number of such messages from a specific user reaches a certain 
threshold, I want to be able to block that user from sending outgoing messages. 
 This latter part is simple enough but getting the bounces information in a way 
I can read it programmatically has got me baffled.

Is that even possible?

Thanks,
