I need to deploy DKIM on a single stand-alone Exchange 2013 server we have on premises. is there a Microsoft tool for crating the DKIM key, a plug - in or a PowerShell script?
I have a Exchange server behind a ASA firewall and a smart host for secure messaging in between, for two .com domains.
can someone vouch for the plugin from emailarchitect.net? or offer another solution?
thanks in advance
