Hi I have a distribution group with multiple sub domains but can't able to send email on them from eternally. I have added a subdomain sub.abc.com and un check the automatic update box and added the email address in there but wont work at all did distribution group does support multiple email address with different sub domains.?

1. Do you get ANY NDR bounce back? 2. Are there any restrictions on who can send email to that DL? 3. Which version of Exch you using? 4. Can internal users send without issue? 5. Try below, search DL in EMC Click the Distribution Group name as you want to set #2. Click the "Properties" #3. Click the "Mail Flow Settings" Tab #4. Click the "Message Delivery Restrictions" item #5. Click the "Properties..." button #6. Uncheck the "Require that all senders are authenticated" item #7. Click "OK" button #8. Click "OK" button againSukh

Are the sub-domains part of your "Accepted Domains"? --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
