Sharper spam filtering.
Tuned to you.
MXFilter catches 99%+ of spam, malware, and phishing, with per-domain Bayesian learning that sharpens based on your messages, not someone else's.
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.
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)
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
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
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
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.
Make it yours.
