I have an Exchange 2003 organization authoritative for domain1.com (Main domain) domain2.com and domain3.com.
- Domain1.com and Domain2.com can receive emails ok from external senders.
- Domain3.com cannot receive emails (Error: Delivery is delayed to these recipients or groups)
- Domain3.com can receive emails OK from internal senders
Troubleshooting steps:
- NSLOOKUP: MX records for domain3.com pointing to the same mail server as domain1.com and domain2.com
- Domain added to Email Addresses Policy
- Checked users able to receive email from any sender (As they are receiving on the the first two domains)
I'm not a Ex2K3 person so I might have been overlooking something. Can you guys give a hand with this?
