SpamWeeder Premium is the per-domain inbound filtering service at the center of the StrataMail filter lineup, operated and supported by the Webservio engineering team. It sits in front of your mail server, scanning every inbound message before delivery and stopping spam, phishing, and malware before they ever reach your users — without the false positives that frustrate them.
SpamWeeder is compatible with any mail server or hosted email platform — StrataMail, Microsoft 365, Google Workspace, on-premise Exchange, or any SMTP-capable system.
What Is SpamWeeder Premium?
SpamWeeder Premium is a cloud-based email security gateway priced per domain. When activated, your domain's MX records point to SpamWeeder's filtering infrastructure. All inbound email passes through SpamWeeder first. Clean messages are delivered to your mail server immediately. Spam, malware, and known-bad messages are blocked, quarantined, or tagged based on your configured policies. Every deployment includes a brandable quarantine portal — IT administrators and users manage quarantine and filtering rules online without involving IDC engineering for routine changes.
Accuracy Through Tuning
SpamWeeder Premium combines reputation-based filtering, multi-layer spam heuristics, and content analysis, then tunes the policy to your real mail flow during onboarding. That tuning is what keeps false positives — legitimate email incorrectly flagged as spam — low enough for production business use. For organizations switching from a weaker filter, the reduction in inbox spam volume is usually obvious within the first days.
Email Spooling: Up to 4 Days
SpamWeeder Premium includes email spooling — when your primary mail server is unreachable, SpamWeeder accepts and holds inbound messages rather than bouncing them. Messages are queued for up to four days and delivered when your server recovers. Spooling protects the mail; it does not give your users a way to send and receive during the outage. For that, pair SpamWeeder with StrataMail Email Continuity: SpamWeeder's multi-destination delivery routes mail to the continuity service automatically when your server is down, with no DNS change. For longer queue protection without webmail access, StrataMX Backup holds mail for up to 30 days.
Included with StrataMail Shared
Every StrataMail mailbox sits behind spam filtering. SpamWeeder Premium is included with StrataMail Shared hosting, and it is available as a discounted option for StrataMail VPS customers or as a standalone service for any other mail platform. If your organization needs deeper protection against targeted phishing and business email compromise, VIPRE Email Security and Proofpoint Essentials are available in the same lineup.
MX Protection Explained
SpamWeeder's MX protection model replaces your mail server's public address with SpamWeeder's filtering servers in DNS. This conceals your actual mail server address from the public internet — attackers cannot directly target a mail server they cannot identify. The filtering infrastructure is hardened to handle the high-volume attack traffic that would overwhelm a standard business mail server.
White-Label Through the Partner Program
SpamWeeder Premium is available to IT providers, MSPs, and agencies through the StrataMail partner program.
