Spam, viruses and in-house AI
Combine spam filtering and virus scanning with Peravix’s own AI detection. A layered approach helps assess unwanted and potentially harmful incoming messages before they reach the destination mail service.
Peravix MailGuard · Inbound email security
A smarter filter.
Before your inbox.
Give business email another line of defence. Peravix MailGuard checks incoming messages for spam and viruses, combines filtering with in-house AI detection, and forwards messages that pass to your existing mail service.
The journey to your inbox
Checks first. Delivery second.
MailGuard sits in front of your destination mail server. Your domain’s MX records direct incoming email through Peravix before onward delivery.
- 01 / Receive
Mail arrives at Peravix
The sender’s mail service follows your domain’s MX records to our filtering servers.
- 02 / Inspect
Layered filtering
Spam filters, virus checks and our in-house AI detection assess incoming messages.
- 03 / Decide
Apply your policies
Messages are handled according to the filtering policy agreed for your organisation.
- 04 / Deliver
Continue to your mailbox
Messages that pass the checks are forwarded to your configured destination mail server.
No email filter can guarantee that every threat will be detected. MailGuard is one layer of protection alongside secure accounts, endpoint security and staff awareness.
Built by Peravix
Protection that learns from real feedback.
Technology and everyday user decisions work together to inform future filtering.
A purpose-built web interface
Use our custom web UI to interact with your email filtering and mark unwanted messages as spam. We agree the access and controls appropriate for your users during setup.
Your users help train the filters
Marking messages as spam in the web UI provides feedback for future filtering. Junk-folder activity can also contribute where a supported mailbox connection has been configured.
Feedback helps train the filters; it does not guarantee an immediate or identical decision for every similar message.
Fit around your email
A filtering layer, not a new inbox.
MailGuard is designed to sit ahead of your existing email platform. We review your mail service, domain and routing requirements before confirming compatibility and planning the change.
It suits organisations looking for additional inbound protection, a Peravix-managed filtering service and a way for user feedback to inform detection.
Your questions, answered
Inbound email filtering FAQs
What is MX-based inbound email filtering?
MX records tell sending mail servers where to deliver email for your domain. With MailGuard, those records point incoming mail towards Peravix’s filtering servers. Messages are checked before those that pass are forwarded to the agreed destination mail server.
Do we need to change our email addresses?
The filtering service is designed to work with your existing domain and destination mail service rather than replace your email addresses. We check your provider and routing requirements before confirming the setup.
How does user feedback help train the filters?
Users can mark messages as spam in the custom web UI. Moving messages into a junk folder can also provide learning feedback when the relevant supported mailbox connection is configured. We confirm which feedback methods are available for your environment during onboarding.
Does AI detection guarantee that all unwanted mail is blocked?
No. In-house AI detection forms part of a layered filtering process, not a guarantee. Unwanted mail can still get through and legitimate messages can sometimes be flagged. User feedback helps inform future filtering decisions.
Can this work with Microsoft 365 or our own mail server?
We review the destination platform, its inbound routing requirements and domain configuration before confirming compatibility. Tell us whether you use Microsoft 365, hosted email or your own mail server when you enquire.
Does MailGuard include email hosting or outgoing filtering?
This service covers inbound email filtering. Mailbox hosting, outgoing email controls and wider account security are separate requirements that we can discuss as part of your overall email setup.
