External exchange port 25 once all mailboxes are moved..
Hi, We have moved all our mailboxes to Office 365. Our MX records point to Office 365. Is there any reason to have the external port 25 open on our in house Hybrid server? Thanks

an MFP printer would be internal to our network. I am looking at the old inbound port 25 that email came into.
