Your domain name and email system are often the most important parts of your business identity. If your DNS, email authentication or admin access is weak, criminals may be able to spoof your domain, target clients or abuse compromised mailboxes.
Solway Web Consulting helps Sydney small businesses review and harden email, DNS and domain settings without turning a practical issue into an enterprise project.
Why domain email security matters
Business email compromise, invoice redirection and domain spoofing often begin with email trust. For small businesses, the practical goal is to make spoofing harder, reduce avoidable misconfiguration and secure the accounts that control mail flow.
SPF, DKIM and DMARC in plain English
SPF helps say which mail servers are allowed to send email for your domain.
DKIM adds a cryptographic signature so receiving mail systems can check whether a message was authorised by your domain.
DMARC tells receiving mail systems what to do when SPF or DKIM checks fail, and can provide reporting that helps identify abuse or misconfiguration.
These controls are not magic protection, but they are important foundations for reputable business email.
DNS and registrar hygiene
The review can cover the registrar account, DNS hosting, name servers, mail routing, stale records, administrator access, MFA and recovery paths. For many small businesses, the domain registrar is overlooked even though it controls the website, email and public identity of the business.
Common issues
- Missing or overly broad SPF records
- DKIM not enabled for Microsoft 365, Google Workspace or hosted mail
- DMARC absent, misconfigured or left in monitoring forever
- Old mail services still present in DNS
- Domain registrar access held by a former supplier
- Admin accounts without MFA
- No written record of DNS changes
What Solway Web Consulting checks and fixes
Solway Web Consulting can review your current DNS and email posture, explain the risk in plain English, correct SPF/DKIM/DMARC records where appropriate, document changes and recommend stronger account security for administrators.
The work is compatible with Microsoft 365, Google Workspace and many hosted email providers, subject to access and provider limitations.
