Inbound filtering from $2.95 a month

Clean mail, before it reaches your server.

Mail Protection by SpamExperts sits in front of the mail server you already run. Your MX records point at the filter, mail is checked on the way in and on the way out, and only the mail you want carries on to your own infrastructure. The engine is SpamExperts, which reports blocking more than 99.93% of spam with false positives in roughly 0.001% of cases.

Before you order

This is for domains that already run their own mail server.

Mail Protection is a gateway. It filters mail and passes it on, so it needs somewhere to pass it to. It does not provide mailboxes.

If you do not run a mail server, business email is the better answer. Every mailbox comes with spam and virus filtering and archiving already switched on, so there is nothing extra to buy or point anywhere.

How it works

Your mail takes one extra hop.

Nothing about your mailboxes changes. The filter is a layer in front of your existing setup, not a replacement for it.

1. Arrives

You point your MX records at our filter. Mail for every address on the domain comes to us first, and we give you the exact records to publish.

2. Filtered

The sending server is validated first, so known bad senders are refused outright. What gets through is then scored, and spam, phishing and malware are stopped.

3. Delivered

Anything legitimate is relayed to your mail server as normal. Your mailboxes, users and client settings stay exactly as they are.

Pricing

Three filters, priced separately.

Inbound filtering is the default and the only one you need to start. Add the others when they earn their place. Prices are live in USD and cover every address on the domain.

What is in it

Built for people who run mail.

The engine is SpamExperts, which protects mail for hosting companies and businesses worldwide and keeps its own threat data current in real time.

Two-stage filtering

The sending server is checked before the message is accepted, then the message itself is scored. Most junk never gets accepted in the first place.

Quarantine you can act on

Release a message, release and train the filter so it learns, or release and allow the sender. Bulk actions when there is a pile of them.

Allow and block lists

Rules per domain or per address, so a supplier can reach one person without opening the door for everyone.

Logs you can search

Find a message by sender, recipient or subject. See what happened to it, and release it without leaving the dashboard.

Continuity while yours is down

If your mail server is unreachable, mail is held and delivery is retried. It is not bounced back at the sender the moment your server has a bad day.

Archive when you need it

Every message kept, encrypted and searchable, with an audit trail. Useful when a regulator, a lawyer or a customer asks what was said.

Setup

What you actually have to do.

One DNS change for inbound. Outbound needs one on the sending side too. We give you the exact values in your dashboard rather than leaving you to find them.

Point your MX records

Replace your MX records with the ones we provide. Remove the old ones, because leaving them in place means only some of your mail gets filtered.

Trust the delivery host

Tell your mail server to accept mail from the filter. Otherwise it may treat your own filtered mail as suspicious.

Adjust SPF if you send through us

Outbound filtering sends mail through our relay, so your SPF record needs to say so. We give you the value to paste.

Two things surprise people during the switch. Your first few messages can be delayed by ten to fifteen minutes while the filter learns your mail server, and that settles down after the first handful. DNS changes can also take up to 48 hours to be seen everywhere, so filtering may not cover every sender immediately.

Questions

Mail Protection, answered.

Who actually runs the filtering?
The filtering engine is SpamExperts, an email security platform used by hosting companies and businesses worldwide. We provision it on your domain and support it for you, so you deal with us and we deal with the platform, including the quarantine, the DNS records you need and anything that goes wrong at three in the morning.
Do I need my own mail server for this?
Yes. Mail Protection is a gateway, so it filters mail and passes it on to a mail server you already run. It does not provide mailboxes. If you do not run your own mail server, our business email is the better fit, because filtering and archiving are already part of every mailbox.
Will this change my mailboxes or my users?
No. Your mailboxes, users and existing settings stay where they are. The filter is a layer in front of your mail server, and legitimate mail is relayed to it as before. Only your DNS records change.
Which filter should I start with?
Inbound filtering. It is the default and it stops the vast majority of what people are actually complaining about. Add outbound filtering if you want protection against a compromised mailbox sending spam in your name, and add archiving when you need a retained, searchable copy of your mail.
Why does archiving need outbound filtering?
Archiving keeps a copy of mail in both directions, so both directions have to be routed through the filter before there is anything complete to archive. We will not sell you archiving on its own, and the order form will not let you combine them that way.
What happens to mail that gets blocked?
Most of it lands in quarantine, where you can review it and release anything that should not have been stopped. Releasing it can also train the filter, so the same message from the same sender is less likely to be stopped next time. Quarantined messages are deleted automatically after two weeks. A message refused at the connection stage is never accepted at all, so that one cannot be recovered.
Can I allow a sender that keeps getting blocked?
Usually yes, with an allow list entry that applies to the whole domain or to a single address. There is one exception worth knowing. An allow list entry turns off content filtering for that sender, but it cannot override a sender that is on a real time blocklist or whose mail server is badly configured. Those messages can still be refused.
Can I move across from another spam filter?
Yes. The change is the same one you would make for any filter, which is updating your MX records. We give you the records to publish, and it is worth keeping your old filter in place until mail is flowing cleanly through the new one.
Is there a contract?
No. Mail Protection is billed monthly or annually and you can stop it whenever you like. If you stop, your MX records need to point back at your mail server so mail keeps arriving.

Get started

Filter the mail before it costs you a morning.

Take it out on one domain first. If you do not run a mail server at all, start with business email instead and get filtering from day one.
