I use cloudflare's email remailer. i.e emails are mailed from from & to my Gmail via cloudflare. Using a custom email domain.

Does this mean that my emails will no longer be sent?

DMARC only requires SPF or DKIM to pass, so the mail will pass of it's DKIM signed.

I think you can set a ARC header for forwarders.

I think they set it automatically, at least based on https://blog.cloudflare.com/email-routing-subdomains
