I set up a distribution group so when email comes in for user "A" it forwards to the distribution group, there are 2 users in the distribution group both local addresses. but when I try to send email to user "A" I get an error:
Your message wasn't delivered due to a permission or security issue. It may have been rejected by a moderator, the address may only accept e-mail from certain senders, or another restriction may be preventing delivery.
