Question RE disable banned recipient notification per domain

[Jakob Curdes]

Hi, we run a medium-size mailserver with severals domains and an 
amavisd/postfix setup. We now would like to disable the notification 
mail to the local recipient of a banned file, but not globally as you 
would do it with the variable
$warnbannedrecip, but just for one of our domains. I think it must be 
possible somehow but I found no example how to do this. I suppose I need 
to pass some sort of array where the entry for one domain is set to 
false !?
I would be glad if somebody could give me a hint.

Best regards, Jakob Curdes
