Why MXFilter

Always evolving.

The filter protecting you today isn't the one you had last month. The engineers who built it keep sharpening it, against new threats and your own false positives.

Always tuning

Report a false positive and the engineers who wrote the filter see it. Tunings go live same day, sometimes same hour. Not on a vendor's SLA.

Tuned for you

Per-domain Bayesian learning kicks in once a user trains enough ham and spam. Your inbox learns your conversations, not the global average.

AI-augmented

Beyond rules and Bayes, a local LLM reads message intent to catch novel phishing and social engineering. Runs in-house, so your mail never leaves our network.

Rule Engine

Phenomenal cosmic powers

From simple matches to deep regex.

Build simple rules to catch domains and senders, or complex regex that matches anywhere in the email body and headers.

Resellers add filters at their level, automagically applied across every domain they manage.

*Regex license not included.

  • Customize blocking action (hard reject or quarantine)
  • Match both sender & receiver
  • Full raw message matching
  • Intuitive Regex Tester (you'll need it)

Per-Domain Bayes

Filtering built for you

Customized to your inbox.

Most filters share one Bayesian brain across every customer. We don't. Once a user trains enough ham and spam, MXFilter spins up a per-domain Bayesian model that sharpens against your real conversations.

  • Activates automatically once trained on enough mail
  • The longer you use it, the sharper it gets
  • Falls back to our global model until then, so there's never a cold start

Score Tuning

Surgical precision

Tune scores where they matter.

Every verdict carries a score behind the scenes, and you can move those numbers. Loosen thresholds so newsletters stop getting eaten. Tighten them on a domain getting hammered by campaigns.

  • Adjust at the reseller level or down to a single domain
  • Tweak individual rule weights without touching defaults
  • Live preview of any change before it hits the queue

Quarantine & Reports

Your users in the loop

Quarantine, reports, and digests.

Held mail lands in a searchable quarantine where users can preview and release it without filing a ticket. Scheduled digests show each person what got held, with one-click release, so most never log in at all.

  • Full quarantine with search, preview, and release
  • Report builder for traffic, scores, and threats
  • Daily/weekly digest emails with one-click release

Domain Protection

Spoof-proof your domain

DMARC reports show you exactly who's sending mail as you. MTA-STS makes sure inbound mail arrives encrypted, enforced rather than best-effort. Both come standard, the kind of thing standalone services bill monthly for.

DMARC Dashboard
Rogue senders Flagged on sight
DMARC Dashboard: Aggregate reports from Google, Microsoft, Yahoo and the rest, distilled into pass/fail trends and sending sources you can actually read.
Every Report, Searchable
Every Report, Searchable: Drill into any report, search by sender, filter by date range, and download the raw XML when you need receipts.
Reseller Fleet View
Reseller Fleet View: DMARC health across every domain you manage, then drill down the moment one needs attention.
Hosted MTA-STS
Hosted MTA-STS: We host the policy. Add a CNAME and a TXT record and inbound mail arrives over verified TLS connections, with reports to prove it.
