When the ExternalDNSAdapterEnabled parameter is set to $True, DNS lookups of destinations that are outside the Exchange organization are performed by using the DNS settings of the external network adapter specified by the value of the ExternalDNSAdapterGUID parameter. If you want to specify a custom list of DNS servers that are only used for external Exchange 2007 DNS lookups, you must specify the DNS servers by using the ExternalDNSServers parameter, and you must also set the value of the ExternalDNSAdapterEnabled parameter to $False. The default value of the ExternalDNSAdapterEnabled is $True.

ExternalDNSAdapterGUID

Optional

System.Guid

This parameter specifies the network adapter that has the DNS settings that are used for DNS lookups of destinations that exist outside the Exchange organization. The concept of an external network adapter and an internal network adapter is only applicable in a multi-homed Exchange 2007 server environment. Typically, a multi-homed Exchange 2007 server is only used with the Edge Transport server role in a perimeter network. When no particular network adapter is specified as the network adapter for external DNS lookups, the value of the ExternalDNSAdapterGUID parameter is 00000000-0000-0000-0000-000000000000, and external DNS lookups are performed by using the DNS settings of any available network adapter. You may enter the GUID of a specific network adapter to use for external DNS lookups. The default value of the ExternalDNSAdapterGUID parameter is 00000000-0000-0000-0000-000000000000.

Note:

If the value of the ExternalDNSAdapterEnabled parameter is set to $False, the value of the ExtermalDNSAdapterGUID parameter is ignored, and the list of DNS servers from the ExternalDNSServers parameter is used.

• B (bytes)
  
• KB (kilobytes)
  
• MB (megabytes)
  
• GB (gigabytes)
  

Unqualified values are treated as bytes. The valid input range for this parameter is 0 to 2147483647 bytes. If you specify a value of 0, only the original message headers are included in the external DSN.

ExternalDSNReportingAuthority

Optional

Microsoft.Exchange.Data.SmtpDomain

This parameter specifies what the server name should be in the machine-readable part of the external DSN message. The default value is the authoritative domain that is specified during installation.

ExternalDsnSendHtml

Optional

System.Boolean

This parameter specifies whether external DSN messages should be sent by using HTML or if messages should be sent in plain text. The default value is $True.

ExternalIPAddress

Optional

System.Net.IPAddress

This parameter specifies the IP address that is used in the Received: message header field for every message that travels through the Edge Transport server or Hub Transport server. The IP address in the Received: header field is used for hop count and routing loop detection. When an Edge Transport server is protected by a router or firewall that uses Network Address Translation (NAT), NAT disrupts the Edge Transport server's hop count and routing loop calculations. When the Edge Transport server is protected by NAT, the RFC 1918 private, non-routable IP addresses that are typically used by the server's network adapters do not match the public, routable IP addresses that are defined in the domain's public DNS MX records. The IP addresses that are assigned to the internal or external network adapters of the Edge Transport server can be determined by using the Get-NetworkConnectionInfo cmdlet. The IP address specified by the ExternalIPAddress parameter overrides the external network adapter's actual IP address. Typically, you would want to set the value of the ExternalIPAddress parameter to match the value of your domain's public MX record. The default value of the ExternalIPAddress parameter is blank. This means the actual IP address of the external network adapter is used in the Received: header field.

ExternalPostmasterAddress

Optional

System.Nullable

This parameter specifies the e-mail address in the From: header field of an external DSN message. The default value is $Null. On a Hub Transport server, the value of the external postmaster e-mail address is postmaster@<defaultaccepteddomain>. If an Edge Transport server has not yet been through the EdgeSync process, and ExternalPostmasterAddress is set to $Null, the external postmaster e-mail address on the Edge Transport server is postmaster@<edgetransportserverfqdn>. If an Edge Transport server has completed the EdgeSync process, and ExternalPostmasterAddress is set to $Null, the external postmaster e-mail address on the Edge Transport server is postmaster@<defaultaccepteddomain>. To override the default behavior, you can specify an e-mail address for the ExternalPostMasterAddress parameter.

InternalDNSAdapterEnabled

Optional

System.Boolean

This parameter specifies one or more DNS servers that Exchange 2007 uses for internal DNS lookups. When the InternalDNSAdapterEnabled parameter is set to $True, DNS lookups of destinations that are inside the Exchange organization are performed by using the DNS settings of the internal network adapter specified by the value of the InternalDNSAdapterGUID parameter. If you want to specify a custom list of DNS servers that are only used for internal Exchange 2007 DNS lookups, you must specify the DNS servers by using the InternalDNSServers parameter, and you must also set the value of the InternalDNSAdapterEnabled parameter to $False. The default value of the InternalDNSAdapterEnabled parameter is $True.

InternalDNSAdapterGUID

Optional

System.Guid

This parameter specifies the network adapter that has the DNS settings that are used for DNS lookups of servers that exist inside the Exchange organization. The concept of an internal network adapter and an external network adapter is only applicable in a multi-homed Exchange 2007 server environment. Typically, a multi-homed Exchange 2007 server is only used with the Edge Transport server role in a perimeter network. When no particular network adapter is specified as the network adapter for external DNS lookups, the value of the InternalDNSAdapterGUID parameter is 00000000-0000-0000-0000-000000000000 and internal DNS lookups are performed by using the DNS settings of any available network adapter. You may enter the GUID of a specific network adapter to use for internal DNS lookups. The default value of the InternalDNSAdapterGUID parameter is 00000000-0000-0000-0000-000000000000.

Note:

If the value of the InternalDNSAdapterEnabled parameter is set to $False, the value of the IntermalDNSAdapterGUID parameter is ignored, and the list of DNS servers from the InternalDNSServers parameter is used.

MessageTrackingLogMaxDirectorySize

Optional

Microsoft.Exchange.Data.Unlimited

This parameter specifies the maximum size of the message tracking log directory. When the maximum directory size is reached, the server deletes the oldest log files first.

The maximum size of the message tracking log directory is calculated as the total size of all log files that have the same name prefix. Other files that do not follow the name prefix convention are not counted in the total directory size calculation. Renaming old log files or copying other files into the message tracking log directory could cause the directory to exceed its specified maximum size.

When the Hub Transport server role and the Mailbox server role are installed on the same server, the maximum size of the message tracking log directory is not the specified maximum size because the message tracking log files that are generated by the different server roles have different name prefixes. Message tracking log files for the Hub Transport server role or Edge Transport server role begin with the name prefix MSGTRK. Message tracking log files for the Mailbox server role begin with the name prefix MSGTRKM.

• KB (kilobytes)
  
• MB (megabytes)
  
• GB (gigabytes)
  
• TB (terabytes)
  

Unqualified values are treated as bytes. The value of the MessageTrackingLogMaxFileSize parameter must be less than or equal to the value of the MessageTrackingLogMaxDirectorySize parameter. The valid input range for either parameter is 1 to 9223372036854775807 bytes. If you enter a value of unlimited, no size limit is imposed on the message tracking log files.

MessageTrackingLogPath

Optional

Microsoft.Exchange.Data.LocalLongFullPath

This parameter specifies the location of the message tracking logs. The default location is C:\Program Files\Microsoft\Exchange Server TransportRoles\Logs\MessageTracking. In a single copy cluster (SCC) environment, move the message tracking log directory to a physical disk resource that is located on the shared storage resource. This enables searches of message tracking logs to continue to function if a failover occurs. If you set the value of the MessageTrackingLogPath parameter to $Null, you effectively disable message tracking. However, if you set the value of the MessageTrackingLogPath parameter to $Null when the value of the MessageTrackingLogEnabled attribute is $True, you will generate event log errors. The preferred method to disable message tracking is to use the MessageTrackingLogEnabled parameter.

The valid input range for either parameter is 1 to 9223372036854775807 bytes. If you enter a value of unlimited, no size limit is imposed on the Receive connector protocol log files.

ReceiveProtocolLogPath

Optional

Microsoft.Exchange.Data.LocalLongFullPath

This parameter specifies the path of the protocol log directory for all the Receive connectors that exist on the server. The default location is C:\Program Files\Microsoft Exchange\TransportRoles\Logs\ProtocolLog\SmtpReceive. Setting the value of this parameter to $Null disables protocol logging for all Receive connectors on the server. However, setting this parameter to $Null when the value of the ProtocolLoggingLevel attribute for any Receive connector on the server is Verbose generates event log errors. The preferred method of disabling protocol logging is to use the Set-ReceiveConnector cmdlet to set the ProtocolLoggingLevel to None on each Receive connector.

RecipientValidationCacheEnabled

Optional

System.Boolean

This parameter specifies whether the recipient addresses that are used by transport agents such as Recipient Filtering are cached. The default value is $True on Edge Transport servers and $False on Hub Transport servers.

ReplayDirectoryPath

Optional

Microsoft.Exchange.Data.LocalLongFullPath

This parameter specifies the path of the Replay directory. The Replay directory is used to resubmit exported messages and to receive messages from foreign gateway servers. The default location is C:\Program Files\Microsoft\Exchange Server\TransportRoles\Replay. If the value of ReplayDirectoryPath is set to $Null, the Replay directory is disabled.

RootDropDirectoryPath

Optional

System.String

This parameter specifies the top-level location of the Drop directory that is used by all Foreign connectors that are defined on a Hub Transport server. The value of the RootDropDirectoryPath parameter may be a local path, or a Universal Naming Convention (UNC) path to a remote server. By default, the RootDropDirectoryPath parameter is blank. This indicates the value of RootDropDirectoryPath is the Exchange 2007 installation folder. The default Exchange 2007 installation folder is C:\Program Files\Microsoft\Exchange Server\. The RootDropDirectoryPath parameter is used with the DropDirectory parameter in the Set-ForeignConnector cmdlet to specify the location for outgoing messages that are going to the address spaces that are defined on the Foreign connector.

RoutingTableLogMaxAge

Optional

Microsoft.Exchange.Data.EnhancedTimeSpan

This parameter specifies the maximum routing table log age. Log files that are older than the specified value are deleted. The default value is 7 days. To specify a value, enter the value as a time span: dd.hh:mm:ss, where d = days, h = hours, m = minutes, and s = seconds. The valid input range for this parameter is 00:00:00 to 24855.03:14:07. Setting the value of the RoutingTableLogMaxAge parameter to 00:00:00 prevents the automatic removal of routing table log files because of their age.

RoutingTableLogMaxDirectorySize

Optional

Microsoft.Exchange.Data.Unlimited

This parameter specifies the maximum size of the routing table log directory. When the maximum directory size is reached, the server deletes the oldest log files first. The default value is 50 MB. When you enter a value, qualify the value with one of the following units:

• B (bytes)
  
• KB (kilobytes)
  
• MB (megabytes)
  
• GB (gigabytes)
  
• TB (terabytes)
  

Unqualified values are treated as bytes. The valid input range for this parameter is 1 to 9223372036854775807 bytes. If you enter a value of unlimited, no size limit is imposed on the routing table log directory.

RoutingTableLogPath

Optional

Microsoft.Exchange.Data.LocalLongFullPath

This parameter specifies the directory location where routing table log files should be stored. The default value is C:\Program Files\Microsoft\Exchange Server\TransportRoles\Logs\Routing. Setting the value of the RoutingTableLogPath parameter to $Null disables routing table logging.

SendProtocolLogMaxAge

Optional

Microsoft.Exchange.Data.EnhancedTimeSpan

This parameter specifies the Send connector protocol log file maximum age. Log files that are older than the specified value are deleted. The default value is 30 days. To specify a value, enter the value as a time span: dd.hh:mm:ss, where d = days, h = hours, m = minutes, and s = seconds. The valid input range for this parameter is 00:00:00 to 24855.03:14:07. Setting the value of the SendProtocolLogMaxAge parameter to 00:00:00 prevents the automatic removal of Send connector protocol log files because of their age.

SendProtocolLogMaxDirectorySize

Optional

Microsoft.Exchange.Data.Unlimited

This parameter specifies the maximum size of the Send Connector Protocol Log directory. When the maximum directory size is reached, the server deletes the oldest log files first. The minimum value is 1 MB. The default value is 250 MB. When you enter a value, qualify the value with one of the following:

• B (bytes)
  
• KB (kilobytes)
  
• MB (megabytes)
  
• GB (gigabytes)
  
• TB (terabytes)
  

Unqualified values are treated as bytes. The value of the SendProtocolLogMaxFileSize parameter must be less than or equal to the value of the SendProtocolLogMaxDirectorySize parameter. The valid input range for either parameter is 1 to 9223372036854775807 bytes. If you enter a value of unlimited, no size limit is imposed on the Send connector protocol log directory.

SendProtocolLogMaxFileSize

Optional

Microsoft.Exchange.Data.Unlimited

This parameter specifies the maximum size of the Send connector protocol log files that are shared by all the Send connectors that exist on a server. When a log file reaches its maximum file size, a new log file is created. The default value is 10 MB. When you enter a value, qualify the value with one of the following:

• B (bytes)
  
• KB (kilobytes)
  
• MB (megabytes)
  
• GB (gigabytes)
  
• TB (terabytes)
  

Unqualified values are treated as bytes. The value of the SendProtocolLogMaxFileSize parameter must be less than or equal to the value of the SendProtocolLogMaxDirectorySize parameter. The valid input range for either parameter is 1 to 9223372036854775807 bytes. If you enter a value of unlimited, no size limit is imposed on the Send connector protocol log files.

SendProtocolLogPath

Optional

Microsoft.Exchange.Data.LocalLongFullPath

This parameter specifies the location of protocol log storage for the Send connectors. The default location is "C:\Program Files\Microsoft Exchange\TransportRoles\Logs\ProtocolLog\SmtpSend". Setting the value of this parameter to $Null disables protocol logging for all Send connectors on the server. However, setting this parameter to $Null when logging the value of the ProtocolLoggingLevel attribute for any Send connector on the server is Verbose or if the IntraOrgConnectorProtocolLoggingLevel parameter is set to Verbose generates event log errors. The preferred method of disabling protocol logging is to use the Set-SendConnector cmdlet to set the ProtocolLoggingLevel parameter to None on each Send connector and to set the IntraOrgConnectorProtocolLoggingLevel parameter to None.

TransientFailureRetryCount

Optional

System.Int32

This parameter specifies the maximum number of immediate connection retries that are attempted when the server encounters a connection failure with a remote server. The default value is 6. The valid input range for this parameter is 0 to 15. When the value of this parameter is set to 0, the server does not immediately attempt to retry an unsuccessful connection, and the next connection attempt is controlled by the OutboundConnectionFailureRetryInterval parameter.

TransientFailureRetryInterval

Optional

Microsoft.Exchange.Data.EnhancedTimeSpan

This parameter controls the connection interval between each connection attempt that is specified by the TransientFailureRetryCount parameter. On a Hub Transport server, the default value of the TransientFailureRetryInterval is 5 minutes. On an Edge Transport server, the default value is 10 minutes. To specify a value, enter the value as a time span: hh:mm:ss, where h = hours, m = minutes, and s = seconds. The valid input range for this parameter is 00:00:01 to 12:00:00.

WhatIf

Optional

System.Management.Automation.SwitchParameter

The WhatIf parameter instructs the command to simulate the actions that it would take on the object. By using the WhatIf parameter, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf parameter.
