As a best practices approach, make sure that on Settings > Control Panel > Network Settings, at the bottom, uncheck the "Enable SMTP Local Server (Inbound)" if this feature is not used, which is to be able to receive email via Exchange Servers. Also if the "Enable SMTP Remote Server (Outbound Relay)" is enabled, make sure that credentials are in place, anonymous connections tend to cause loop/bounce-back issues.
