Purpose
Performs comprehensive email deliverability auditing for a domain. Checks DNS authentication records (SPF, DKIM, DMARC), infrastructure (MX, PTR, TLS), reputation (blacklists), and bulk sender compliance. Generates a health score (0-100) with prioritized fixes.
Input
• Domain name: e.g., rankenstein.cloud, example.com • Optional: Email volume (triggers bulk sender compliance checks if 5,000+ emails/day)
1. SPF Record (Weight: 10%)
What to check: • SPF record exists at TXT <domain> • Valid syntax: starts with v=spf1 • DNS lookup count (max 10, warn at 8+) • Enforcement level: -all (pass), ~all (softfail), ?all (neutral), +all (fail) • No multiple SPF records (causes validation failure) • Includes are efficient and necessary Commands: `bash dig txt <domain> +short | grep "v=spf1"
