How to bypass DKIM Check for specific Domain name

We have enabled DKIM Check on our Server and hence when DKIM check fails EXIM reject the Incoming Email. 

Lets say we have hosted abc.com & xyz.com on our server. When they receive an Email from 123domains.com which fails at DKIM level. 

Now abc.com says even if DKIM fails they still want email to be delivered. Whereas xyz.com is okay with not receiving emails as it fails to verify DKIM. 

We would like to Bypass DKIM Check for abc.com and thus any email that which fails to verify dkim, still they will be able to get it and xyz.com wont get it.

  Hey there!  I don't have a way to do this at this time inside cPanel as the current DKIM whitelist feature is all-or-nothing.  I'm also not finding an easy workaround to this so the best thing to do would be to submit a feature request for this behavior over at features.cpanel.net and then I can bring it up with our team to see if that's something they can get added to the product.

  If you'd like me to submit that request for you I'm happy to do that as well - just let me know!

  Sure thing - I've submitted that through our features site and I'll bring that up with the team during tomorrow's meeting.  Once I have more details I'll be sure to post and let you know.

  Update - at this time, this isn't something we want to add directly to the product.  However, anything is possible if you want to dig into the underworld that is the Exim filter system.

  You should be able to create a block in WHM >> Exim Configuration >> Advanced Editor for the "acl_check_rcpt" section with this:

  warn domains = customer-domain.com
       control = dkim_disable_verify

  and that will enable the dkim_disable_verify option for that domain.

  Additional details on this can be found here: https://www.exim.org/exim-html-current/doc/html/spec_html/ch-dkim_spf_srs_and_dmarc.html

  Please note that cPanel isn't able to help with Exim customizations at this level, so you may need to modify this information a bit to fit your specific purpose.
