Mailchannels integration clarification

[sweet swallow]

Hello! I was just looking though the blog post announcing mailchannels integration and saw this line:

The only constraint currently is that the integration only works when the request comes from a Cloudflare IP address. So it won’t work yet when you are developing on your local machine or running a test on your build server.

I was wondering if that meant that mailchannels just checks if the requester's ip is cloudflare's or there is more security behind it (e.g authorization header that cloudflare adds on)

Thanks in advance!

IIRC MailChannels cut support for their API agreement

So that no longer works the same way

@gleaming bloom Wait what is cloudflare using now?

That’s something else. You can use it to send to Verified Emails

So you can’t just arbitrarily email people with it
