We have a domain that is "Managed by Shopify", exampledomain.com. We've set it up on Shopify that whenever someone sends an email to support@exampledomain.com it will be forwarded to support@exampledomain.zendesk.com. It's been working fine for the longest time, however, I believe, due to the recent email from Shopify regarding DMARCs, our customers started to receive undeliverable messages whenever they responded to our messages.
I've contacted Zendesk Support and was told the issue is with Shopify. I contacted Shopify and was told the issue was with Zendesk.
Anyone who has the same issue?
