Once Integrated Windows Authentication has been enabled globally as per the Security and authentication settings section, each post office can then be configured with specific authentication settings.

The General tab dialog configures the Microsoft Windows domain that post office mailboxes can authenticate against. The name of the mailbox must match the corresponding Windows account name. For example, a mailbox named Administrator will be able to authenticate using the Windows Administrator password.

In simple implementations there is likely to be only one domain, or the authentication will be done against the local machine. More complicated implementations will allow authentication against specific domains (i.e.: if the organization is made up of multiple domains). If you are authenticating against a domain, and the server is not within that domain, the server must have permissions to log in, i.e. you must configure a trust relationship. Errors relating to Windows authentication for mailboxes can be found in the Windows event log.




Use Integrated Windows Authentication

Defines whether the post office can use Windows Authentication.

Use Post Office Name as Windows Domain Name

Select this option if the name of the post office matches the desired Windows Domain Name.

Map this Post Office to the following Domain Name

Defines the Windows Domain Name that the will be used for authenticating this post office’s mailbox users. To authenticate against the local machine, either leave the Domain Name blank or enter a single period (.).

Authenticate against Active Directory

Configures MailEnable to use User Principal Name (UPN) style logins, rather than legacy Windows NT style logins. Both login mechanisms work equally as effectively, except Active Directory hosting of multiple domains in its hierarchy.

Automatically create mailbox if successful login and one doesn’t exist

Allows accounts to be created as users authenticate. If a user enters valid Windows credentials, their mailbox is created automatically. Enabling this option immediately provides access to mailboxes for those who have validated against the specified domain.

Users must authenticate against Windows user and not fall back to MailEnable configured password Enforces a user to only authenticate against the Windows user database and not fall back to the MailEnable authentication database.
Smarthost all outbound email for postoffice This will route all emails for users of this postoffice to the one remote address. This would be used if you need to filter all the outbound email for just the postoffice. It does not affect email going to a local mailbox, just the outbound emails for the users of the postoffice.
IP Address The destination IP address to route through.
Port The port of the destination service. By default this is port 25.
The remote server requires authentication Enable this if you need to authenticate to remote server.
