You manage a Microsoft Exchange Server 2019 organization that sends 100,000 email messages to the Internet daily. The messages are routed through a single smart host by using a single Send connector that has an address space of *.
Your network contains an Active Directory site named Site01 that has all the Exchange servers. You have a disaster recovery site named Site02 that has several SMTP servers.

You need to deliver queued messages to the Internet as quickly as possible.
