Xeams
Millstone, New Jersey, United States
What it is
Xeams is an email server and spam firewall that can operate on its own, in front of another mail server, or in a hybrid setup. It supports SMTP, POP3, and IMAP, alongside email standards including SPF, DKIM, DMARC, and MTA-STS. Its filtering combines sender reputation, authentication checks, attachment and content rules, Bayesian analysis, and virus checks. Quarantined messages remain on the server for 15 days by default and are available through the web interface or an IMAP client. Administrators use a web interface for live monitoring, logs, reports, retention settings, and tiered access. Other tools include Active Directory integration, OAuth 2.0 outbound relaying, REST APIs, event webhooks, campaigns, read receipts, and header sanitization. The Community Edition is free for up to five users in personal hobby use when spam filtering is enabled; spam filtering is otherwise limited to five users. A new installation includes Enterprise features for 30 days, then converts to Community Edition unless licensed. Enterprise pricing varies by tier; support for Enterprise Edition is $300 a year per deployed instance.
