Valid values for this parameter are $true or $false. The default value is $true. When the EightBitMimeEnabled parameter is set to $true, the 8BITMIME EHLO keyword is advertised in the EHLO response to the remote server and is available for use. When the EightBitMimeEnabled parameter is set to $false, the 8BITMIME EHLO keyword isn't advertised in the EHLO response to the remote server and is disabled.

EnableAuthGSSAPI

Optional

System.Boolean

The EnableAuthGSSAPI parameter specifies the advertisement of the Generic Security Services application programming interface (GSSAPI) authentication method, when Integrated Windows authentication is enabled on this connector. If the AuthMechanism parameter contains Integrated, and the EnableAuthGSSAPI parameter is set to $true, the AUTH GSSAPI NTLM keyword is advertised in the EHLO response of the Receive connector. Clients may use Kerberos or NTLM to authenticate with the Receive connector. If the AuthMechanism parameter contains Integrated, and the EnableAuthGSSAPI parameter is set to $false, the AUTH NTLM keyword is advertised in the EHLO response of the Receive connector. Clients may use only NTLM to authenticate with the Receive connector.

If you have Internet Information Services (IIS) messaging servers that authenticate with this Receive connector, you should set the value of the EnableAuthGSSAPI parameter to $false. Authentication with computers running Microsoft Exchange Server 2003 aren't affected by the value of the EnableAuthGSSAPI parameter. Exchange 2003 servers use the authentication methods advertised in the X-EXPS keyword. The X-EXPS keyword is advertised in the EHLO response of the Receive connector when the AuthMechanism parameter contains ExchangeServer.

The valid values for this parameter is $true or $false. The default value is $false. By default, the EnableAuthGSSAPI parameter is set to $true only on the default Receive connector Client <Server Name> created only in the Transport service on a Mailbox server.

Enabled

Optional

System.Boolean

The Enabled parameter specifies whether to enable the connector. Valid values for this parameter are $true or $false. The default value is $true. Use the Enabled parameter to enable or disable the connector.

EnhancedStatusCodesEnabled

Optional

System.Boolean

The EnhancedStatusCodesEnabled parameter specifies whether the ENHANCEDSTATUSCODES EHLO keyword is advertised in the EHLO response to the remote server and is available for use. Valid values for this parameter are $true or $false. The default value is $true. When the EnhancedStatusCodesEnabled parameter is set to $true, the ENHANCEDSTATUSCODES EHLO keyword is advertised in the EHLO response to the remote server and is available for use. When the EnhancedStatusCodesEnabled parameter is set to $false, the ENHANCEDSTATUSCODES EHLO keyword isn't advertised in the EHLO response to the remote server and is disabled. The ENHANCEDSTATUSCODES extension provides enhanced error and status information in delivery status notification messages sent to remote servers.

ExtendedProtectionPolicy

Optional

Microsoft.Exchange.Data.Directory.SystemConfiguration.ExtendedProtectionPolicySetting

The ExtendedProtectionPolicy parameter specifies how Extended Protection for Authentication is implemented on this Receive connector. By default, this parameter is set to None. The ExtendedProtectionPolicy parameter may have the following values:

  • None   Extended Protection for Authentication isn’t used.

  • Allow   Extended Protection for Authentication is used only if the connecting host supports it. Otherwise, connections are established without Extended Protection for Authentication.

  • Require   Extended Protection for Authentication is required for all incoming connections to this Receive connector. If the connecting host doesn't support Extended Protection for Authentication, the connection is rejected.

Extended Protection for Authentication enhances the protection and handling of credentials when authenticating network connections using Integrated Windows authentication. Integrated Windows authentication is also known as NTLM. We strongly recommend that you use Extended Protection for Authentication if you are using Integrated Windows authentication.

Fqdn

Optional

Microsoft.Exchange.Data.Fqdn

The Fqdn parameter specifies the FQDN used as the destination server for connected messaging servers that use the Receive connector to send incoming messages. The value of this parameter is displayed to connected messaging servers whenever a destination server name is required, as in the following examples:

  • In the default SMTP banner of the Receive connector

  • In the EHLO/HELO response of the Receive connector

  • In the most recent Received header field in the incoming message when the message enters the Transport service of a Mailbox server or an Edge server

  • During TLS authentication

The default value of the Fqdn parameter is the FQDN of the Mailbox server or Edge server that contains the Receive connector.

NoteNote:
Don't modify the FQDN value on the default Receive connector Default <Server Name> that's automatically created in the Transport service of a Mailbox server. If you have multiple Mailbox servers in your Exchange organization and you change the FQDN value on the Default <Server Name> Receive connector, internal mail flow between Mailbox servers will fail.

LiveCredentialEnabled

Optional

System.Boolean

This parameter is reserved for internal Microsoft use.

LongAddressesEnabled

Optional

System.Boolean

The LongAddressesEnabled parameter specifies whether the Receive connector accepts long X.400 email addresses. The X.400 email addresses are encapsulated in SMTP email addresses by using the Internet Mail Connector Encapsulated Address (IMCEA) encapsulation method.

When the value of this parameter is $false, the maximum length for a complete SMTP email address is 571 characters.

When the value of this parameter is $true, the following changes are made:

  • The XLONGADDR keyword is advertised in the EHLO response of the Receive connector.

  • The accepted line length of an SMTP session is increased to 8,000 characters.

  • Valid long addresses are accepted by the MAIL FROM and RCPT TO SMTP commands.

Therefore, X.400 email addresses can be up to 1,860 characters long after IMCEA encapsulation.

The valid values for this parameter are $true or $false. The default value is $false. You can modify this parameter only on Receive connectors configured in the Transport service on a Mailbox server.

MaxAcknowledgementDelay

Optional

Microsoft.Exchange.Data.EnhancedTimeSpan

This parameter isn't used by Microsoft Exchange Server 2013. It's only used by Microsoft Exchange 2010 servers in a coexistence environment.

The MaxAcknowledgementDelay parameter specifies the maximum period the transport server delays acknowledgement until it verifies that the message has been successfully delivered to all recipients. When receiving messages from a host that doesn't support shadow redundancy, an Exchange Server 2010 transport server will delay issuing an acknowledgement until it verifies that the message has been successfully delivered to all recipients. However, if it takes too long to verify successful delivery, the transport server will time out and issue an acknowledgement anyway.

To specify a value, enter it as a time span: dd.hh:mm:ss where d = days, h = hours, m = minutes, and s = seconds.

The default value is 30 seconds.

ProtocolLoggingLevel

Optional

Microsoft.Exchange.Data.ProtocolLoggingLevel

The ProtocolLoggingLevel parameter specifies whether to enable or disable protocol logging for a Receive connector. A value of Verbose enables protocol logging for the connector. A value of None disables protocol logging for the connector. The default value is None. The location of the Receive connector protocol logs for all Receive connectors configured on a Mailbox server or an Edge server is specified by using the ReceiveProtocolLogPath parameter of the Set-TransportService cmdlet.

ProxyEnabled

Optional

System.Boolean

This parameter is reserved for internal Microsoft use.

RequireEHLODomain

Optional

System.Boolean

The RequireEHLODomain parameter specifies whether the remote computer must provide a domain name in the EHLO handshake after the SMTP connection is established. Valid values for this parameter are $true or $false. The default value is $false. When the RequireEHLODomain parameter is set to $true, the remote computer must provide a domain name in the EHLO handshake after the SMTP connection is established. If the remote computer doesn't provide the domain name, the SMTP connection is closed.

RequireTLS

Optional

System.Boolean

The RequireTLS parameter specifies that all messages received by this connector require TLS transmission. Valid values for this parameter are $true or $false. The default value is $false. When the RequireTLS parameter is set to $true, all messages received by this connector require TLS transmission.

Server

Optional

Microsoft.Exchange.Configuration.Tasks.ServerIdParameter

The Server parameter specifies the server on which the new Receive connector is created.

ServiceDiscoveryFqdn

Optional

Microsoft.Exchange.Data.Fqdn

The service discovery fully-qualified domain name (FQDN).

SizeEnabled

Optional

Microsoft.Exchange.Data.SizeMode

The SizeEnabled parameter specifies whether the SIZE SMTP extension is enabled. Valid values for this parameter are Enabled, Disabled, or EnabledwithoutValue. The default value is Enabled. When the SizeEnabled parameter is set to Enabled, the SIZE SMTP extension is enabled, and the maximum allowed message size value from the MaxMessageSize parameter is advertised in the EHLO banner. When the SizeEnabled parameter is set to Disabled, the SIZE SMTP extension isn't used, and the maximum allowed message size value is never disclosed to the remote server. When the SizeEnabled parameter is set to EnabledWithoutValue, the SIZE SMTP extension is enabled. However, the maximum allowed message size value from the MaxMessageSize parameter isn't advertised in the EHLO banner. This allows the message to bypass message size checks for authenticated connections between Mailbox servers. The SIZE SMTP extension is defined in RFC 1870. The SIZE SMTP extension enables the source server to declare the size of the inbound message to the target server. It also allows the target server to declare the maximum message size that it's allowed to accept to the sending server. If the advertised size of the inbound message exceeds the value in the MaxMessageSize parameter, the Receive connector responds to the remote server by using an error code and closes the connection.

SuppressXAnonymousTls

Optional

System.Boolean

The SuppressXAnonymousTls parameter specifies whether this Receive connector supports the standard TLS encryption for incoming connections. By default, all communications between servers is protected with TLS. However, if you need to disable TLS on a specific connection in your organization, you can create a specific Receive connector and set the SuppressXAnonymousTls parameter to $true. The default value is $false.

Before you can set this parameter to $true, you must use the Set-TransportService cmdlet to set the UseDownGradedExchangeServerAuth parameter to $true on the server this Receive connector is configured.

TarpitInterval

Optional

Microsoft.Exchange.Data.EnhancedTimeSpan

The TarpitInterval parameter specifies the amount of time to delay an SMTP response to a remote server that may be abusing the connection. Authenticated connections are never delayed in this manner. The default value is 5 seconds.

To specify a value, enter it 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 from 00:00:00 through 00:10:00. When you set the value to 00:00:00, you disable the tarpit interval.

TlsCertificateName

Optional

Microsoft.Exchange.Data.SmtpX509Identifier

The TlsCertificateName parameter specifies the X.509 certificate to use with TLS sessions and secure mail. Valid input for this parameter is [I]Issuer[S]Subject. The Issuer value is found in the certificate's Issuer field, and the Subject value is found in the certificate's Subject field. You can find these values by running the Get-ExchangeCertificate cmdlet.

TlsDomainCapabilities

Optional

Microsoft.Exchange.Data.MultiValuedProperty

The TlsDomainCapabilities parameter specifies the capabilities this Receive connector will make available to specific hosts outside your organization. TLS with certificate validation is used to authenticate remote hosts before these capabilities are offered.

To specify capabilities for a domain, use the following syntax:

<domain name 1>:<capability 1, capability 2,…,capability N>

If you're specifying capabilities for multiple domains, list the configuration for each domain in quotation marks ("), separated by commas. For example:

"contoso.com:AcceptOorgProtocol","fabrikam.com:AcceptOorgProtocol,AcceptOorgHeader"

You can configure the capabilities for non-TLS encrypted incoming connections using the special "NO-TLS" domain.

You can configure the following capabilities for a domain:

  • AcceptOorgProtocol

  • AcceptOorgHeader

TransportRole

Optional

Microsoft.Exchange.Data.Directory.SystemConfiguration.ServerRole

The TransportRole parameter designates the server role associated with this connector. Types include FrontendTransport and HubTransport. Typically used to specify the server role when you host multiple server roles on a single computer.

WhatIf

Optional

System.Management.Automation.SwitchParameter

The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, 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 switch.

To see the input types that this cmdlet accepts, see Cmdlet Input and Output Types. If the Input Type field for a cmdlet is blank, the cmdlet doesn’t accept input data.

To see the return types, which are also known as output types, that this cmdlet accepts, see Cmdlet Input and Output Types. If the Output Type field is blank, the cmdlet doesn’t return data.
