DMARC Setup · Brighton
DMARC Setup in Brighton
Configuring email authentication so a Brighton 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 Brighton — 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 East Sussex?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Brighton and the surrounding East Sussex area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Brighton businesses do you usually work with?
- Design-led briefs from a market that judges craft closely, plus hospitality and visitor systems for the local economy. Beyond that we work across Digital & Creative, Tourism & Hospitality, Higher Education and Retail.
- Do you cover the areas around Brighton?
- Yes — we work throughout South East, including London, Southampton. Brighton is an urban area of roughly 290,000+, and we take on work across the wider East Sussex region rather than the city boundary alone.
