a) You use before-queue filters. Use a content filter that supports different per-recipient policies. There is no Postfix support for different before-queue filters for multi-recipient mail. b) You use after-queue filters. Instead of using content_filter within a single Postfix instance, use multiple Postfix instances, and use transport_maps to select the per-recipient filter between the two instances. The before/after queue terminology is defined in http://www.postfix.org/CONTENT_INSPECTION_README.html For Postfix multiple instance management see http://www.postfix.org/MULTI_INSTANCE_README.html Wietse
