Delivery failed to distribution groups
Hi,
Recently we installed Exchange 2010.
I set Support distribution group and in Mail flow settings->Message Delivery Restrictions I set All senders and uncheck “Require that all senders are authenticated checkbox.” Nevertheless, when I send message from my Gmail account I get the following error:
550 Recipient addresses rejected: Relaying denied (state 14).
The internal users can post mail to this group.

Does the Support DG contain any external contacts?
If you check again the “Require that all senders are authenticated" checkbox can you send mail to this distribution group?
ASKER
1.Support distribution group has the valid support@domain.com address.Is it what you mean when say external contact?
2.Checking “Require that all senders are authenticated" didn't help.

I forgot to tell you that this option prevents external senders from sending messages to distribution groups.
can you post the full bounce back error
1.) no, I mean does the DG contain any contacts or are they all mailboxes?
ASKER
To MegaNuk3 :
Support DG and all other DGs contan mailboxes only (Valid users in DC ) and not contacts.

Do you have any AV or spam filtering that external messages go through? You might need to add the DG email address into the recipient whitelist.
