-### Terraform Provider Rate Limiting
-
-{/* Public reference: https://github.com/WATonomous/terraform-provider-email/issues/1 */}
-
-We use a [custom Terraform provider](https://github.com/WATonomous/terraform-provider-email/) for managing outgoing emails.
-Currently, the provider is a simple wrapper around an SMTP client.
-The SMTP server we use appears to have a rate limit.
-It errors out when we try to send more than a few emails in quick succession.
-
-We would like to add rate limiting to the provider. [Here's the ticket for this feature](https://github.com/WATonomous/terraform-provider-email/issues/1).

 [^assume-round-robin]: We are assuming that there's perfect DNS round-robin or random selection.
 [^similar-reliability]: It's slightly less reliable than Cloudflare's Zero-Downtime Failover, since there's a delay between when the host goes down and when the DNS record is removed. However, this is still much better than the current situation, where the DNS record of a downed host is never removed.
