Direction-aware archiving
Archive inbound, outbound or both — per domain — with sensible opt-out defaults, so you keep exactly what you need.
Continuity & archiving
Never lose an email — or the ability to send one
Security is only half the job. mxflo keeps a searchable copy of the mail that matters and keeps delivery running even when a node or a backend goes down.
Search & resend
Retrieve an archived message and re-deliver it in seconds — perfect for the "I lost that email" support ticket.
Quarantine retention
Held and quarantined mail is retained and reviewable, so a false positive is never gone for good.
Isolated archive store
Long-term mail archive on redundant storage, kept separate from your live mail platform.
Encrypted backups
Nightly encrypted backups of configuration and data, so recovery is a restore — not a rebuild.
Active-active edge HA
Multiple edges accept mail simultaneously, with automatic MX failover so a single node loss never stops delivery.
Resilience by design
Delivery keeps going when something breaks
mxflo runs on a multi-edge architecture with prioritised MX records and multi-IP egress. If a backend is temporarily unreachable, mail queues safely and resumes automatically — and you can watch queue depth and age from the console.
- Prioritised, multi-edge MX with automatic failover
- Safe queuing and retry when a backend is unavailable
- Queue-by-reason and age telemetry in the dashboard
- Multi-IP egress to protect deliverability
