Even legitimate invoices and enquiries can be flagged as spam when sender authentication is incomplete or several systems send email on behalf of one domain. A DNS audit should distinguish mail routing from authentication.
What to check first
Confirm the MX records receive mail. Inventory each sender including Microsoft 365, website contact forms, CRM and transactional mail. Review SPF alignment, DKIM signing and DMARC policy, then verify the actual headers of sent messages.
An example from everyday UAE business operations
A business may use Microsoft 365 for employee mail and a separate platform for website enquiries. The second service needs its own authorised signing configuration, while the domain should still publish only one valid SPF record.
Free tools to use
These Techvenation tools can help you organise the assessment. Check each result against equipment specifications, your service provider and your own environment before changing production systems.
- DNS & Email Checker — MX, SPF, DMARC, DKIM and DNS records.
- MX Lookup — Check mail exchanger records and priorities.
- SPF Checker — Find SPF records and flag common configuration problems.
- DMARC Checker — Inspect DMARC policy, reporting and enforcement level.
- DKIM Checker — Look up a DKIM TXT record using a supplied selector.
- DNS Record Lookup — Inspect A, AAAA, MX, TXT, NS, CNAME and SOA records.
- DNS Propagation Checker — Compare DNS answers from your server, Google Public DNS and Cloudflare 1.1.1.1.
How to use the findings
Make DNS changes gradually, keep a rollback record, and test Gmail and Outlook recipients. Moving directly to DMARC reject without reporting visibility can interrupt legitimate delivery.
Common mistakes to avoid
Creating multiple SPF TXT records; thinking a DKIM selector is the same for every provider; assuming DNS propagation is immediate. These checks are estimates and practical diagnostics, not independent certification, security clearance or a replacement for an authorised technical assessment.
Next steps for your UAE business
Write down what you checked, what changed and who will own the action. If you support multiple locations, keep the scope and service hours consistent between teams. Collect screenshots or reports without exposing employee credentials, customer records or security secrets.
