DKIM and Exchange 2016
Have any of you setup DKIM on a exchange server? I am looking for a way to set it up. I looked at a lot of things on the web, but don't trust free advice to install software on my exchange server.

Keep in mind DKIM signing will be changing soon.
Be sure the signing server you choose supports simultaneous RSA1024 + ED25519 signing... if highest Delivery/Inboxing is your goal.
And... only use RSA1024, never RSA2048, as many Mailbox Providers run only RSA1024 decoding, so using RSA2048 will dramatically decrease message deliverability.

IS that set in the DKIMSigner software?
Yes, you can choose the key length in the gui
At this point, dual signing requires custom code.
Whether or not... "IS that set in the DKIMSigner software?" supports dual signing...
Refer to this code's docs or open a support ticket with the developers asking if this is possible.
