Help on configuring exchange server to use sophos utm9 as smarthost

hi,

my email is working fine. it can send and receive mails

i noticed that mails is not logged on sophos mail manager. so i search the sophos community for answers and found that i should use sophos utm9 as smarthost.

heres what i did:

i configure my exchange server to use the firewall local ip as smarthost

disable smtp nat

on email protection>smtp>routing

on email protection > smtp > host based relay i put the local ip of mail server and enable Scan Relayed (outgoing messages)

other settings is set to default.

after saving the config, i cant send and receive emails on this settings, so i revert it back to my working config.

heres what i saw on smtp log
