Managed Email in Derry

Managed email for Derry organisations, where authentication decides whether your messages arrive at all. SPF, DKIM and DMARC records tell receiving providers which senders are legitimate — and a policy tightened without accounting for every system that sends on your behalf will quietly discard mail you needed delivered.

Why this comes up

The problem

A stricter policy was applied and invoices sent through the accounting system stopped reaching customers.

What you get

What we deliver

  • Every legitimate sender identified before any policy is tightened
  • SPF, DKIM and DMARC configured and moved to enforcement gradually
  • DMARC reports monitored, since these reveal senders nobody remembered
  • Delivery failures surfaced rather than left in a queue nobody reads
  • Mailbox and licence position reviewed as staff join and leave
  • Retention and archiving set against your actual obligations

Managed Email in Derry — common questions

Why does authentication cause delivery failures?
Because it works by exclusion. Once a policy tells receivers to reject anything not authenticated, every system sending as your domain must be included — and the ones people forget are the invoicing platform, the CRM and the marketing tool, all of which then stop arriving.
How should a policy be introduced?
In stages, with reports first. Starting in monitoring mode produces reports showing every source sending as your domain, including several you had forgotten, and only then is it safe to move to quarantine and eventually to rejection.
What do the reports tell you?
Who is sending as you. That includes your own systems, legitimate third parties and occasionally somebody spoofing your domain — all useful, and the first category is invariably longer than anyone in the organisation would have predicted.
What about mailboxes for leavers?
They need a defined process, because the default is to keep paying. Converting to a shared mailbox, forwarding for a period and eventually archiving are all reasonable, whereas leaving a licensed mailbox active indefinitely is both a cost and an unnecessary access point.
Do you work with businesses across County Londonderry?
Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Derry businesses do you usually work with?
Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
Do you cover the areas around Derry?
Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
