Email security & deliverability in New Lynn
Email is where most attacks start and where most business is still done. We filter out the phishing and fake invoices before staff see them, lock down your domain so nobody else can send as you, and fix the settings that send your own mail to clients' junk folders.
Onsite technicians cover New Lynn. Most problems are fixed remotely first; when a job needs hands, a technician comes to you.
Email security & deliverability for New Lynn businesses
New Lynn has become a dense town centre built around its transport interchange and shopping mall, with new apartment and mixed-use buildings, medical and allied health practices, education providers and offices, while older light industrial streets nearby hold manufacturers and trade businesses.
Businesses moving into new mixed-use buildings get modern fibre but often a small comms cupboard shared with building systems, so equipment needs to be compact and well ventilated. Health and education providers also handle personal information about patients and students, which calls for individual accounts, careful permissions and devices that can be wiped if lost.
We put those records in place carefully. Every service that sends as you, such as your accounting package, website forms and newsletter tool, is found and included first, so tightening the policy doesn't block your own invoices. Then we add filtering for incoming mail and show staff how to report anything odd. Finally we keep watching the DMARC reports, so a new service sending as you, or someone trying to forge your address, is spotted and dealt with rather than discovered when a client complains.
Our technicians attend New Lynn offices and practices for setups, networks and hardware, and help remotely with everyday problems. Moves into new premises are planned and quoted in writing.
What's included
Phishing and malware filtering
Incoming mail scanned for malicious links, attachments and fake sign-in pages, with links checked again when they are clicked.
DKIM signing
Microsoft 365 and your other sending services set to sign outgoing mail with your domain, so receivers can verify it.
DMARC rollout
A reporting-only policy first, then a gradual move to quarantine and reject once reports show all your genuine mail passes.
Impersonation protection
Rules that flag mail pretending to come from your directors, your domain or lookalike domains with a letter swapped.
SPF records
One correct SPF record listing every service that legitimately sends for you, kept within the lookup limits that break many records.
Junk folder fixes
We trace why your mail is being filtered, from missing records to a listed address or a website form sending as you, and correct it.
Is it right for your New Lynn office?
Email security is worth a look if:
- Clients tell you your invoices or quotes end up in junk
- Someone received a fake invoice that appeared to come from your address
- Staff are getting convincing fake Microsoft sign-in emails
- You don't know whether your domain has SPF, DKIM or DMARC
- A large client or bank has asked you to set up DMARC
How getting started works
- Free IT health check. We look at your devices, accounts, backups and network and tell you what we find, in plain English.
- Clear proposal. A written monthly price per user and a list of any fixes, with nothing hidden.
- Handover. We collect admin access and documentation from your current provider and keep your team working.
- Day-one fixes. Security gaps, failed backups and urgent risks are dealt with first.
Email security & deliverability in New Lynn: questions
Our new tenancy has a tiny comms cupboard. Will our equipment fit?
Usually, with compact equipment chosen for the space and a small wall cabinet. We check heat and power availability for low-voltage gear and recommend a layout before anything is ordered.
How should a tutoring or training provider protect student information?
Give staff individual accounts with multi-factor sign-in, keep student records in a secure system rather than spreadsheets on laptops, and back everything up. We set that up and keep it maintained.
Can someone really send email as us?
Without DMARC at a strict policy, yes, it is surprisingly easy. Once the policy is enforced, most receiving mail systems will refuse those forged messages.
How long does it take to set up?
Filtering and records are usually set in a day or two. Moving DMARC to full enforcement normally takes a few weeks of watching reports, so nothing legitimate is caught.
Isn't Microsoft 365's built-in filtering enough?
It catches a lot, but the default settings are not as strict as they could be. We review and tighten them, and on the Managed and Complete plans add extra email security and phishing filtering.
What are SPF, DKIM and DMARC in plain English?
SPF is a list of who can send email for your domain. DKIM is a digital signature on each message. DMARC ties them together and tells receiving servers whether to accept, quarantine or reject mail that fails, and sends you reports about it.
