Description

The Add-DnsServerResourceRecordMX cmdlet adds a Mail Exchanger (MX) resource record to a Domain Name System (DNS) zone.

The MX resource record provides the name for a mail server for a domain. If there are multiple MX resource records for a domain, the client attempts to contact mail servers in the order of preference from lowest value to highest value.

Examples

Example 1: Add an MX resource record

PS C:\> Add-DnsServerResourceRecordMX -Preference 10  -Name "." -TimeToLive 01:00:00 -MailExchange "mail.contoso.com" -ZoneName "contoso.com"

This command adds an MX record named RecordNameMX for the zone western.contoso.com with a preference of 123. The mail exchanger is MAILSrv1.

Parameters

-AgeRecord

Indicates that the DNS server uses a time stamp for the resource record that this cmdlet adds. A DNS server can scavenge resource records that have become stale based on a time stamp.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-AllowUpdateAny

Indicates that any authenticated user can update a resource record that has the same owner name.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet.

For more information about Windows PowerShell background jobs, see about_Jobs.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

Type:CimSession[]
Aliases:Session
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ComputerName

Specifies a DNS server. If you do not specify this parameter, the command runs on the local system. You can specify an IP address or any value that resolves to an IP address, such as a fully qualified domain name (FQDN), host name, or NETBIOS name.

Type:String
Aliases:Cn
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-MailExchange

Specifies an FQDN for a mail exchanger. This value must resolve to a corresponding host (A) resource record.

Type:String
Position:3
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-Name

Specifies the name of the host or child domain for the mail exchange record. To add an MX resource record for the parent domain, specify a dot (.)..

Type:String
Position:2
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Preference

Specifies a priority, from 0 to 65535, for this MX resource record. A service attempts to contact mail servers in the order of preference from lowest priority value to highest priority value.

Type:UInt16
Position:4
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Type:Int32
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-TimeToLive

Specifies the Time to Live (TTL) value, in seconds, for a resource record. Other DNS servers use this length of time to determine how long to cache a record.

The Start of Authority (SOA) record defines the default TTL.

Type:TimeSpan
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-VirtualizationInstance

Specifies the virtualization instance in which the zone will be added. A virtualization instance is logical partition in a DNS Server, which is capable of independently hosting zones and zone scopes. Same name zones and zone scopes can be hosted in different virtualization instances. This parameter is optional and if not provided it will add the zone into the default virtualization instance which is functionally equivalent to a standard DNS server.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type:SwitchParameter
Aliases:wi
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-ZoneName

Specifies the name of a DNS zone.

Type:String
Position:1
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-ZoneScope

Specifies the name of a zone scope.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:True
Accept wildcard characters:False
