Spam blocked at the edge.
Before it reaches your server.
Network-level antispam filters inbound and outbound mail at the gateway — spam never loads your server, never fills your queue, and never costs you processing time.
Filtered at the gateway — not after it arrives.
Most spam filters run on the server — the mail still arrives and gets processed. Our antispam runs at the network edge, so filtered mail never reaches your Cloud Cube at all.
Inbound protection — Rspamd
All inbound mail is scored by Rspamd before delivery. Spam, phishing, and malware attachments are rejected at the SMTP level — they never enter your mail queue.
Outbound protection — MailChannels
Outbound mail routes through MailChannels, which filters outbound spam before delivery. If a compromised account sends spam, it's caught at the gateway — not after your IP ends up on a blacklist.
IP reputation maintained automatically
Because your server's IP is never the outbound sender, your IP reputation is protected by design — not by manual intervention after a blacklisting incident.
A blacklisted IP can take your email offline for days.
IP reputation issues from outbound spam are one of the most common and disruptive email problems on self-managed servers. Gateway filtering prevents them by design.
No blacklist incidents
Your server IP is never exposed as an outbound mail sender. Blacklisting simply can't happen from your IP.
Server resources protected
Spam that never arrives doesn't consume CPU, RAM, or disk I/O — your server stays fast.
Better deliverability
Mail sent through MailChannels reaches inboxes — not spam folders. Legitimate email gets where it's going.
Included free
Network-level antispam is included on every Cloud Cube. No mail filtering add-on required.
