Creator emails dropped by domains with DMARC p=reject or p=quarantine

Creator emails dropped by domains with DMARC p=reject or p=quarantine

Is there a way to send DMARC aligned emails from zohocreator?  The organizations I work with have strict DMARC policies and I don't believe the emails coming from Creator are aligned. There's not a way to "whitelist" as other articles have suggested. Is there a way to enable DKIM signing for my organizations?

For reference, I'm seeing emails coming from 
135.84.80.180 sendera180.zohocreator.com
135.84.80.182 sendera182.zohoRECRUIT.com
135.84.80.183 sendera183.zohoRECRUIT.com 

If there's not a way to allow DKIM signing for my domains, is there a way to change the application's settings to be FROM: zohocreator.com instead? 

Thank you
