Sharper mail filtering.
Tuned for 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 — 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, in-house LLM reads message intent to catch novel phishing and social engineering. 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
- Your newsletters, your vendors, your patterns
- Falls back to global model until then — never a cold start
Surgical Precision
Tune scores where they matter.
Push every newsletter past your finance team's filter. Tighten the threshold on a domain that's seeing campaigns. Adjust at the reseller level for whole portfolios, or down to a single domain when you need precision.
- Reseller-level and domain-level score overrides
- Adjust individual rule weights without touching defaults
- Live preview of how a change affects the queue
Your Users in the Loop
Quarantine, reports, and digests.
A full quarantine system with searchable history, a built-in report builder, and scheduled digest emails so users see what was held — without ever logging into the panel.
- Full quarantine with search, preview, and release
- Report builder for traffic, scores, and threats
- Daily/weekly digest emails with one-click release
