🔒 No security concerns identified

⚡ Recommended focus areas for review Configuration Consistency Ensure that the new CNAME and DKIM records are correctly configured and do not conflict with existing DNS records. Verify that the TTL values are consistent with the domain's DNS policy. SPF Record Update Review the updated SPF TXT record to ensure it includes all necessary mail servers and does not inadvertently allow any unauthorized servers.

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Possible issue	Correct the DKIM selector in the CNAME record to ensure proper email authentication Ensure that the CNAME record for DKIM (mail_autonomys_cname_dk) uses a valid DKIM selector. The current selector 607 might be a typo or incorrectly formatted. dns/autonomys-xyz.tf [96-103] resource "cloudflare_record" "mail_autonomys_cname_dk" { - name = "607._domainkey.mail" + name = "<correct_selector>._domainkey.mail" comment = "CNAME DKIM record pointing to beehiiv" proxied = false ttl = 3600 type = "CNAME" - value = "607.domainkey.u47499917.wl168.sendgrid.net" + value = "<correct_selector>.domainkey.u47499917.wl168.sendgrid.net" zone_id = data.cloudflare_zone.autonomys_xyz.id } Suggestion importance[1-10]: 7 Why: The suggestion addresses a potential issue with the DKIM selector, which is crucial for email authentication. Ensuring the selector is correct is important for the proper functioning of DKIM, though the suggestion is not directly actionable as it requires verification of the correct selector.	7
Best practice	Standardize TTL values across DNS records to enhance DNS management and predictability Verify the consistency of TTL values across all DNS records to ensure uniform caching behavior and avoid potential DNS resolution issues. dns/autonomys-xyz.tf [85-128] resource "cloudflare_record" "mail_autonomys_cname" { ... - ttl = 3600 + ttl = <uniform_ttl_value> ... } resource "cloudflare_record" "mail_autonomys_cname_dk" { ... - ttl = 3600 + ttl = <uniform_ttl_value> ... } resource "cloudflare_record" "mail_autonomys_cname_dk_2" { ... - ttl = 3600 + ttl = <uniform_ttl_value> ... } resource "cloudflare_record" "mail_autonomys_spf" { ... - ttl = 3600 + ttl = <uniform_ttl_value> ... } resource "cloudflare_record" "mail_autonomys_beehiiv_txt" { ... - ttl = 3600 + ttl = <uniform_ttl_value> ... } Suggestion importance[1-10]: 5 Why: While the suggestion to standardize TTL values is a good practice for consistent DNS behavior, the existing TTL values are already uniform at 3600. Therefore, the suggestion does not provide a significant improvement over the current implementation.	5
