Custom delivery failure messages

Hi all!!

Question…

We have a mailing group that we want to limit the its usage to only a few people/groups. We have changed the group document ACL from “All Readers and above” to explicit members. When someone who is not listed expicitly sends to that group, the get a delivery failure. This is just what we want.

Is it possible to modify the message in the delivery failure so that anyone who sends to this group will get the custom message?

I know I can create a custom delivery failure message in the configuration document, but won’t that send the custom message with ANY delivery failure? We want to send the one custom message to whoever sends to that group and leave the default message for everyone else.

Is this possible??

as always,
