Add-DnsServerResourceRecordMX

Adds an MX resource record to a DNS server.

Syntax

Parameter Set: Add0
Add-DnsServerResourceRecordMX [-ZoneName] <String> [-Name] <String> [-MailExchange] <String> [-Preference] <UInt16> [-AgeRecord] [-AllowUpdateAny] [-AsJob] [-CimSession <CimSession[]> ] [-ComputerName <String> ] [-PassThru] [-ThrottleLimit <Int32> ] [-TimeToLive <TimeSpan> ] [-Confirm] [-WhatIf] [ <CommonParameters>]




Detailed 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.

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.

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.
