Hi CK,
Prerequisites
- Set up Public DNS MX record for each SMTP domain for which you accept e-mail from the Internet. Each MX record should resolve to the Internet-facing server that receives e-mail for your organization.
- Send and Receive connectors should be configured, so that the Exchange organization can send e-mail to and receive e-mail from the Internet.
Create Accepted Domains:
New-AcceptedDomain -Name "domain1" -DomainName domain1.com -DomainType Authoritative
Create Accepted Domains for every domains
Now we need to configure the email address policy for the newly created authoritative domains:
New-EmailAddressPolicy -Name “EPolicyDomain1” -IncludedRecipients UserMailbox -ConditionalDepartment “Recipient Container name” -Priority 1 -EnabledEmailAddressTemplates “SMTP:@domain1.com”
Apply the email address Policy:
Update-EmailAddressPolicy -Identity “EPolicyDomain1"
