Rules with IP addresses

[Caza Henha]

Hi Jules,
 
Thanks for the answer, I presumed that would be the case, but I was thinking that as our postfix configuration has transport maps it does actually know before sending the mail to our application server what the destination IP address is. Does this mean then that something like the following would be necessary:
 
To:   support at example.com  store   //Ticketing server
To:   issues at example.com    store   //Ticketing server
....
To:   application1 at example.com  delete //App Server 1
To:   application2 at example.com  store  //App Server 2
...
To:   user at example.com      delete //Exchange server
To:   user at example.com      delete //Exchange server
.....
FromOrTo: default               deliver //Public Mail server
 
Bearing in mind that there are 1000s of different email address permutations going to the app servers (writing a script to create the rules is easy) would there be any performance problems with Mailscanner reading these files? Also when using an IP address in the "From" could you direct me to information from the question below:
