Hi. Does Microsoft support a scenario where SMTP port 25 is blocked outbound for all IP addresses, except for EOP IP addresses, in your local corporate network, as listed here?:

What Im asking I guess, is the IP addresses listed in this Technet article also inbound to EOP, when you define yourdomain-com.mail.protection.outlook.com as smarthost in a Send Connector in Exchange.

Thanks in advance:)

Hi,

I don't really understand what's your intention?
