Email Security Gateways
Alternatives to Xeams
Xeams covers the mail-server job as well as filtering: it can operate independently, guard another server, or combine both roles. SMTP, POP3, and IMAP support sit alongside DKIM, SPF, DMARC, and MTA-STS. Filtering draws on reputation, authentication checks, content and attachment rules, Bayesian analysis, and virus checks. Its web console handles monitoring, logs, reports, retention, and tiered administration. Quarantine remains available through the web or IMAP, while outbound options include DKIM signing, REST APIs, event webhooks, campaigns, read receipts, and header sanitization.

Choosing instead of Xeams
Alternatives make sense when that breadth, deployment model, or cost does not fit. Xeams offers a free Community Edition for personal hobby use up to five users, paid support at $300 per year per instance, and tiered Enterprise pricing from $1.6667 per user per month; a new installation receives 30 days of Enterprise features. It runs across Linux, macOS, Windows, web, API, and self-hosted environments. Compare full mail-server needs with gateway-only protection, the authentication and encryption methods required, platform coverage, collaboration features, and whether you want self-managed software or a hosted service.
