+TF/02 The control = fakereject ACL modifier now has a fakedefer counterpart,
+ which works in exactly the same way except it causes a fake SMTP 450
+ response after the message data instead of a fake SMTP 550 response.
+ You must take care when using fakedefer because it will cause messages
+ to be duplicated when the sender retries. Therefore you should not use
+ fakedefer if the message will be delivered normally.
