Hoping someone could help me out. Sites for all accounts are up but none can send or receive email except locally. If I test sending an email to one of the accounts through an external source such as Hotmail, I IMMEDIATELY get a message back from hotmail saying: This is an automatically generated Delivery Status Notification. Delivery to the following recipients failed. user@mydomain.com.

Please let me know if you have any ideas what could be wrong...i assume it is something wrong with exim but it seems to be running just fine.

Thanks in advance for your help.
