Email Workers Issue with Email Replies on Subdomain

[sonic thicket]

I am following the instructions on https://developers.cloudflare.com/email-routing/email-workers/reply-email-workers/ to set up reply emails.

It functions correctly when the sender sends an email to the top-level domain. However, I encounter an error saying Error: mail from is not from the correct domain if the email is sent to a subdomain.

I have ensured that the MX and TXT records are configured for both the top-level domain and the subdomain.

Is email reply not supported for subdomains yet?

Blast from the past. but did you ever find a solution for this?

Ran into this myself. From my testing, it looks like it's still an issue

From what I end up gathering I don't think it's possible out of the box.

I thiiiiink if you have an Enterprise account, what you can do is treat every sub domain as his own "domain" (heavy quotes against that)
