I have found that inbound mail to distributions groups (Ex07) are not being delivered. Running a trace, I am seeing they are failing on LDAP match. I tracked it down to the qroup query not working. We are using the default query. Running a test, it fails. I think that is the problem. I can mail the group internally just fine.
Anyone have a good query string that will check for distribution groups? Below is the query being used. Thanks for the help.
