Dkimsigner on 2 servers

Versions

• Windows Server Version: 2008 R2 Enterprise
• Exchange Version: 2010 v14.03.xx
• Installed DKIM Exchange Version: [Your version]

Description

Hi,

If I have two mail servers that work in mirror, do I have to install the plugin on both?

[Deckard99]

If you mean cluster/DAG by "mirror", than yes you have to install it on both of your servers. you can choose to use one certificate for each server (than you need two DNS entries - selectors) or you use the same certificate on both, than you need just one selector.

[Deckard99]

BTW: you can't use v3.4 because it dropped Exchange 2010 support. https://github.com/Pro/dkim-exchange/releases/tag/v3.4.0

Hello Deckard99, I am currently setting up a DAG as well and I use the same SSL certificate in both Exchange servers. I copied the "keys" folder after install on the DAG but it fails to load (there is no entry in the Domains window. How could I just use the same keys on both servers? Thank you!

[Deckard99]

You have to copy the settings file as well. not just the keys

Working now sorry. I had to restart the Transport service.

Great job!

Thank you!

In my case, i got a Exchange CAS server (i.e. CAS01) and two mailbox database server (say it MDB01 and MDB02). I don't know which server i need to install the DKIM? I tried to install it on top of CAS01 and it seems that i stop at the step of "Restarting Exchange Transport Service". If i installed DKIM on both database server, then i need to have two TXT entries in the public DNS record ??

Howdy,

You'll need to install it on both mailbox servers unless your Send Connector(s) for external mail has been scoped to a specific server. You can either share the same signing key between both mailbox servers or set up a signing key per mailbox server (different selectors for each) which will require two TXT records in public DNS for DKIM verification.
