I'm setting up a dev agency to do some freelance work and I wanted to route the emails to my Fastmail inbox, this will allow me to keep all my emails within one place and it's all included in the plan I have with Fastmail.

I set up the email with Cloudflare to route all emails sent to that domain but I ran into an issue that was a first for me, below is a cleaned up version of the error:

Unknown error: transient error (451): 4.7.1 <DATA>: Data command rejected: wildwoodpixels.com is too new, temporarily blacklisted - RLR813 - ip=<104.30.8.144>, host=<i-bee.email.cloudflare.net>, helo=<i-bee.email.cloudflare.net>, from_domain=<wildwoodpixels.com>

After digging through some forums, I realized it's not a Cloudflare issue but instead an error thrown by Fastmail. In short, Fastmail will reject any domains not added to its Domains list (Settings โ†’ Domains). So setting up the DNS records in Cloudflare allowed me to do this.

Unfortunately, I have not yet found a way to route all emails through Cloudflare and then redirect them to Fastmail.
