+===== DKIM =====
+<note important>Exchange 2019 (on-prem) does not verify incoming DKIM signatures or sign outgoing by default.</note>
+==== Receiving ====
+We currently rely on MailCleaner (inbound mail filtering) to verify DKIM signatures as Exchange does not do so.
+==== Sending ====
+:!: This free tool will sign outgoing messages for the domains you specify.
+<note tip>The GUI configuration tool is not added to the Start Menu but is located here: "C:\Program Files\Exchange DkimSigner\Configuration.DkimSigner.exe"</note>
