Syntax

Get-DkimSigningConfig
   [[-Identity] <DkimSigningConfigIdParameter>]
   [<CommonParameters>]

Description

DKIM in Microsoft Office 365 is an email authentication method that uses a public key infrastructure (PKI), message headers and CNAME records in DNS to authenticate the message sender, which is stamped in the DKIM-Signature header field. DKIM helps prevent forged sender email addresses (also known as spoofing) by verifying that the domain in the From address matches the domain in the DKIM-Signature header field.
