HI,
I've setup a transport rule to bounce back emails for emails in a specific DL. See below:

However, the rule does not work if there's a mail flow forwarding enabled for that account. See below:

If I disable the forwarding rule, the transport rule works as expected.
I did my research but could only find reports of issues if there's a forward rule in the user's outlook but the behavior isn't the same here (and its set to match address on header or enveloppe already anyways).
Is there something I can do to make this work? We need the forwarding rule for internal users and some automated stuff with hardcoded emails (I know that's bad, but beyond me).
Thanks.
