I didn’t advertise the distribution list address to outside of the domain. But the problem is that there’s someone who is outside of the domain got the address of the group mail and sent spam mails to the group mail. Could you please instruct me how to stop all those mail address sent to the internal group mail from outside. For the matter that you have showed me, it didn’t work well.
