I am receiving the below Intrusion Prevention Alert message every 5 minutes or so.

172.20.1.1 (AstaroDevice01) is my Internet-facing ASG320
Destination IP address: 172.20.1.210 (ExhangeServer01) is my internal Exhange server
AstaroDevice01 is permitted to relay inbound e-mail to ExhangeServer01. Any idea what this message means? There are messages sitting in the Spool, quarantine, etc.
