terraform-cloudflare-fastmail-email

MX, SPF, DKIM and DMARC records with MTA-STS policy (via terraform-cloudflare-mta-sts) for email hosted by Fastmail.

This creates cloudflare_record resources for MX, SPF, DKIM, DMARC and MTA-STS of the given zone_id suitable for fastmail.com. A Cloudflare Worker as part of the terraform-cloudflare-mta-sts dependency serves the MTA-STS policy.

The SPF policy includes Fastmail by default and rejects all others (-all), additional terms can be specified using the spf_terms variable.

The DMARC policy is set to reject and you must provide an email address for DMARC Aggregate and Failure reports through the dmarc_rua and dmarc_ruf variables respectively. Similarly, a TLS aggregate reporting location (mailto: or https:) must be specified in the tlsrpt_rua variable.

Usage

resource "cloudflare_zone" "example_com" {
  zone = "example.com"
}

module {
  source = "rsclarke/fastmail-email/cloudflare"

  zone_id   = cloudflare_zone.example_com.id
  zone_name = cloudflare_zone.example_com.name

  dmarc_rua = ["[email protected]"]
  dmarc_ruf = ["[email protected]", "[email protected]"]
  spf_terms = ["-ip4:192.0.2.0/24", "+ip6:2001:DB8::/32"]

  mta_sts_mode    = "enforce"
  mta_sts_mx      = ["mx.example.net"]
  mta_sts_max_age = 604800
  tlsrpt_rua      = ["mailto:[email protected]", "https://example.org/mta-sts/report"]
}
