Hosting Terms

What is DMARC?

DMARC in plain English — the meaning, the comparison, and why it matters to anybody running a website.

Straight answer first

DMARC is the policy sitting on top of SPF and DKIM — it tells receivers what to do with mail that fails those checks, and sends you reports on what they saw.

The sections below open it up properly — how it works, why a site owner should care, and a concrete example of it doing its job.

To read, naturally

A _dmarc TXT record sets the policy, and there are three rungs: none for monitoring only, quarantine to send failures to the spam folder, reject to refuse them outright. Aggregate reports come back to you listing every source sending as your domain, the legitimate ones alongside the forgers.

The order of operations matters. Publish p=none first and read the reports until every forgotten sender has revealed itself, then climb the ladder once everything genuine is passing.

The picture that makes DMARC stick

Standing instructions handed to every mailroom in the country about letters bearing your letterhead: if the seal and the courier both fail the check, bin it, and post me a summary each week of what turned up.

Comparisons simplify, naturally — but this one holds together well enough to reason with, and reasoning is the whole point of a glossary.

What is actually at stake

Enforcement is the point where somebody spoofing your domain actually stops getting through. Mailbox providers now increasingly demand DMARC from senders as well, which has moved it from good practice to the price of entry.

You do not need to work at this layer every day. You need to recognise it when it explains something, which is exactly the moment this page earns its keep.

One concrete example

A month of p=none reports turns up a forgotten invoicing tool sending unsigned mail. Once that is fixed and aligned, the domain moves to p=reject, and phishing mail wearing its name stops being delivered anywhere that checks.

Multiply that example by every website on the internet and you have the concept's entire job description in one go.

Where you will meet it on our platform

You will meet it in the control panel and occasionally in a support conversation, usually already set the right way. If this term made sense, the natural next reads are SPF, DKIM, TXT Record and Phishing.

Backups run every day on every plan, and putting a file or a database back takes one click from the panel.

A glossary written by the people on the counter

Every confusing term in hosting turns into a support ticket sooner or later, so we defined the hundred most common ones properly, once, in the plain English we would use across the counter.

Real people answer the counter at any hour, including the awkward questions other hosts wave off as out of scope.

DMARC defined, pictured by comparison and placed in your own control panel — recognise-level in a single read.

Pictures that stick

Each concept gets a comparison you will still remember at the moment you actually need it.

The next reads, mapped

Read on into SPF and DKIM — terms rarely stand alone, so the neighbours are linked.

The stakes spelled out

Not only what it is, but when it turns out to be the answer to a problem you are having.

Grounded in real kit

Examples point at hosting you would actually use, not at an abstract diagram.

Plain English first

Every term defined for people who run sites, not for other sysadmins — jargon translated rather than restated.

First Steps

From choosing to live

1
Find it in your own account
The quickest way to learn a hosting term is to find it in your own panel; five minutes of looking beats an hour of reading about it.
2
Check what the defaults are
Confirm how your account has this set. It is usually right by default here, and now you will know rather than guess.
3
Follow the terms next door
Concepts travel in packs — SPF, DKIM and TXT Record finish this one's picture, and each is a two-minute read away.

Across the Counter

The questions we get asked most

What is in a DMARC report — can anyone read my mail?

No message content ever appears. A report is a set of counts per sending source with the authentication result for each. It is a headcount of who sends as you, which happens to be exactly the knowledge you need before turning enforcement on safely.

How quickly can I go from none to reject?

Weeks, and let the evidence set the pace. You want long enough for the monthly senders — invoice runs, newsletters, an annual mailing — to show up in a report. Jumping to reject early bounces the legitimate sender you had forgotten about, and finding it is what the reports are for.

Are backups included, and can I put one back myself?

A backup is taken daily on every plan, and the restore is yours to run from the panel in minutes — files, databases or both, at three in the morning without waiting on a ticket. Keeping your own copy offsite as well is never a bad habit, and nothing here stops you.

Does the price climb when the term is up?

No. What you pay to order is what you pay to renew, year after year. We do not run teaser rates, so there is no year-two ambush waiting in the calendar, and your bookkeeping can treat the hosting line as a fixed number.

What does round-the-clock support actually stretch to?

People at the counter at every hour, and a scope that takes in the practical work: mailbox setup, DNS records, WordPress trouble, restores. Not 'the server responds, ticket closed'. Ask us something hard before you order — the reply is a fair sample of what you would get afterwards.

What happens to my files if I leave?

The site and the files stay yours. Pull a full backup from the panel whenever you like, before or during cancellation. Domains remain registered in your name for the term you paid for and can move to any registrar once the standard 60-day window has passed.

Is the SSL certificate genuinely free?

On every plan, with nothing held back. The certificate is issued the moment your domain points here and reissues itself well before expiry. The encryption is the same as a paid DV certificate — paid tiers exist only for wildcard coverage or organisation validation, which most sites never need.

Packing up and moving host? Take our checklist.

A plain running order for a move nobody notices: what to copy first, how to carry email across without dropping a single message, when to point DNS, and the two slips behind nearly every hour of downtime we get called about.

Start on a plan with a plain price tag.

From a first website to a rack of servers, moving up is a change to your account rather than a migration.
