2nd post - Cannot use a group to deny smtp

I created a group containing internet address that I want to prevent my users to receive e-mail.group name: deny-smtp

group type: deny list only

In server config. doc. I inserted this group name into field “Deny messages from the following internet addresses/domains” that would stop e-mails coming from any addresses listed in the group.

I had already executed: “tell smtp update config” and “tell router update config”.

It is not blocking at all.

I had also tried restating smtp and router tasks, but it is not blocking anyway.

I had this working before under version 6.0 and 6.0.1. Now with 6.5 it doesnt work.

Any help will be appreciated.
