Most DMARC setups I audit have the record in place but p=none sitting there, which means spoofed mail still gets delivered. The record exists, it's just not enforcing anything. What I'd do: pull your current SPF, DKIM, and DMARC records and check for the common failure points, SPF lookup count hitting the 10-record limit, DKIM selectors not rotating, DMARC alignment gaps between your envelope and header From. Then a spoofing test to see what actually gets through, fix whatever I find on the DNS side, and write up the findings with what was changed and why. 350 SGD for the full audit, fixes, and written report over 3 days. This is an indicative estimate from the brief; I'll give you a firm quote once the scope is confirmed. One thing that'd help me upfront: do you have direct access to your DNS provider to apply changes, or does that go through a third party?

Hi — Mukesh here. I reviewed your project and understand the importance of strengthening your domain’s email security to prevent spoofing, improve deliverability, and ensure full authentication compliance. The key is performing a structured audit of SPF, DKIM, and DMARC alignment, identifying misconfigurations or gaps in DNS records, and validating how your domain behaves across different mail providers. My approach focuses on tightening authentication policies gradually, ensuring legitimate mail flow is not disrupted while improving enforcement against unauthorized senders. A few questions to better understand your setup: Q1 – Which email provider or hosting service are you currently using (Google Workspace, Microsoft 365, cPanel, etc.)? Q2 – Do you already have DMARC reports enabled or any monitoring tools in place? Q3 – Are there multiple sending sources (website forms, CRM, marketing tools) connected to the same domain? Happy to review your current configuration and recommend a safe, step-by-step hardening plan. Best regards, Mukesh

I audit SPF, DKIM, and DMARC configurations and fix email spoofing vulnerabilities like this regularly. I can start immediately and begin reviewing your DNS records and email authentication setup. Do you have access to your domain's DNS management panel (Cloudflare, GoDaddy, etc.)? I'm new to Freelancer.com, but not new to DNS, email security, and server administration (20+ years experience). Are you currently using any third-party email sending services (SendGrid, Mailgun, etc.)? I'll have your email authentication fully audited and secured within 24 hours. You only approve the milestone after testing it yourself. Budget: $207 SGD | Timeline: 24 hours
