Mailchannels: sender is not authorized

I'm getting:

0    "Failed to send email: 550 5.7.1 This sender is not authorized to send from my-site.com. See https://bit.ly/domain-lockdown. cfid=my-site-v3.pages.dev"

0    "Failed to send email: 550 5.7.1 This sender is not authorized to send from my-site.com. See https://bit.ly/domain-lockdown. cfid=my-site-v3.pages.dev"

I have a TXT record with: name: _mailchannels
value: =mc1 cfid=my-site-v3.pages.dev (copied as is from error message) --- Do I need to just wait for DNS to catch up, or am I missing something?

You may want to reconsider mailchannels: https://discord.com/channels/595317990191398933/779390076219686943/1152689451374477483 Your value looks wrong though, should start with v=mc1. Can you share the domain name itself as well?
