email address cannot receive mail from external senders

[Guest2]

We have a group that has an email address assigned, its able to receive email internally but cannot receive mail externally.

On exchange under the group in exchange general 'message restrictions' is set to accept messages from everyone.

I have tested sending a mail to the email from my hotmail account and get a delivery notification failure - Delivery to the following recipients failed... (then the address)

Where would I look to set the address so it can receive external emails?

Thanks

Yep, its server 2003.

This is an automatically generated Delivery Status Notification.

Delivery to the following recipients failed.

******@*******.com

Is there an attachment in the hotmail NDR with more info included?

Dont think so, how would I find this info?

I have clicked everything in hotamail that usually shows all attachments. There is not other info apart from it saying
Delivery to the following recipients failed.

then the address it failed to

Heres one I tried sending from my sky email address...


Delivery to the following recipient failed permanently:

**********@********.com

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: 550 550 Invalid Recipient (state 14).
