Script

function Get-DKIMRecord {
    <#
    .SYNOPSIS
        Get DKIM Record for a domain.
    .DESCRIPTION
        This function uses Resolve-DNSName to get the DKIM Record for a given domain. Objects with a DomainName property,
        such as returned by Get-AcceptedDomain, can be piped to this function. The function defaults to "selector1" as this
        is typically used with Exchange Online.
    .EXAMPLE
        Get-AcceptedDomain | Get-DKIMRecord

        This example gets DKIM records for all domains returned by Get-AcceptedDomain.
