In this section, you can verify the existence of the recipient account on your system for incoming emails to your domain. There are two account control management methods:
- Callout: A test email is sent to the specified incoming server or server IP address to check the existence of the account. If the account exists, the email is then processed.
- LDAP: The recipient account is queried against the specified LDAP database server, and the email is delivered or rejected based on the response.
- Transport: Account verification is performed using the servers or server IP addresses added to this section.
- Order: You can determine whether the account verification in the Transport section is done in the entered order or randomly.
