Exchange 2007: unable to receive external email?

[flynbrian2007]

I am unable to receive external email to my new exchange 2007 server...

What I did:
1. I moved my mailbox from 2003 to 2007
2. Changed the NAT and Access rules on firewall to point to the new server
3. I checked DNS and 67.107.X.X is pointing to email.domain.com and 2003server.domain.com. I changed the 2003server to 2007server in DNS.

Testing:
1. Tested Webmail – it was good
2. Tested my PDA – it was good with no changes required
3. Tested Outlook – it was good after restarting Outlook
4. Sent message to internal 2007 user – it was good
5. Sent message to my Gmail – it was good
6. Sent message from my Gmail to my 2007server email – Email was rejected.

This is the Delivery Status message I received back to my GMail:

Delivery to the following recipient failed permanently: <my email address>
Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 530 530 5.7.1 Client was not authenticated (state 13).

My guess is:
1. Receive connector on 2007 is not configured correctly OR
2. DNS hasn’t resolved yet OR
3. Maybe routing group connectors are conflicting since I made the above changes?

Any help would be great!

Thank you!

You need to configure Receive Connector unless you use Edge Server.

Thanks for the reply...

I have two receive connectors... one that listens on port 25 and one that listens on port 587. I have set the default receive connector permissiongroups to anonymous since I do not have an edge server.

Any ideas...???

What you did should be enough to work. I simulated it in my Virtual Machine, and I received same reject message.

Just double check it to be sure it starts working, or you can create new Receive Connector for that purpose. However, Default Connector with permission for anonymous group is enough to start receive mails.

Do not use the built in receive connectors for inbound Internet traffic. Add a receive connector and grant anonymous permissions.
