[<CommonParameters>] 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.
