DMARC Setup · Swansea
DMARC Setup in Swansea
Configuring email authentication so a Swansea organisation's domain cannot be used to send fraudulent mail. The work is careful rather than difficult — every legitimate sending service has to be authorised first, because moving to enforcement with something missed means your own mail stops arriving.
Why this comes up
The problem
Emails claiming to come from the company are reaching customers and suppliers. The domain has no enforced authentication, so anyone can send as it.
What you get
What we deliver
- Every legitimate sender identified — mail platform, CRM, invoicing, marketing tools
- SPF configured within the lookup limit, which is easy to exceed and breaks silently
- DKIM signing enabled on each sending service
- DMARC published in monitoring mode first, with reports actually reviewed
- Progressive move to quarantine and then reject once reports are clean
- Ongoing report monitoring, since new tools get added and break authentication

DMARC Setup in Swansea — common questions
- What happens if we enforce too early?
- Legitimate mail gets rejected. If your invoicing system or marketing platform was never authorised, its mail fails authentication and disappears — often noticed days later when someone asks why statements stopped arriving. Monitoring first is what prevents that.
- What is the SPF lookup limit?
- SPF permits a maximum of ten DNS lookups, and each included service consumes them. Organisations with several mail tools exceed it without warning, at which point SPF fails silently. Consolidating or flattening the record is a common part of this work.
- Is monitoring mode enough?
- No — it blocks nothing. It produces reports showing who sends as your domain, which is essential preparation, but a domain sitting in monitoring indefinitely is as spoofable as one with no DMARC at all. Enforcement is the point.
- Does this need maintaining?
- Yes. Every new tool that sends on your behalf needs authorising, and teams add them without telling IT. Reviewing DMARC reports periodically catches both unauthorised senders and your own marketing team's new platform before it fails.
- Do you work with businesses across Swansea?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Swansea and the surrounding Swansea area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Swansea businesses do you usually work with?
- Bilingual public-facing systems for institutional clients, and seasonal booking for the Gower tourism trade. Beyond that we work across Higher Education, Healthcare, Manufacturing, Tourism and Public Sector.
- Do you cover the areas around Swansea?
- Yes — we work throughout Wales, including Cardiff, Newport. Swansea is an urban area of roughly 240,000+, and we take on work across the wider Swansea region rather than the city boundary alone.
