Synametrics releases Xeams 10.3 with new AI and web tools

Synametrics Technologies has released Xeams 10.3, adding a new MCP Server for AI assistants, a browser-based mail client and expanded administrative controls. The update is aimed at helping organizations manage email security, automate routine tasks and replace legacy SMTP relay systems with modern authentication.

Why it matters: - Xeams 10.3 pushes the platform deeper into AI-assisted email management, which could reduce manual work for administrators and support teams. - The release also gives organizations a newer option for SMTP relay as legacy IIS SMTP becomes harder to use with modern email systems like Microsoft 365. - The update bundles security, administration and user-access tools into one platform for on-premises and cloud deployments.

What happened: - Synametrics Technologies Inc. released Xeams 10.3 on July 28, 2026. - Xeams is the company’s secure enterprise email server and email security platform. - The release adds an updated Xeams MCP Server for AI assistants and custom AI agents. - The release also introduces Xeams Web Access, a browser-based email client included at no additional cost. - Xeams 10.3 Build 6448 adds new web, queue management, campaign and monitoring features.

The details: - The updated Xeams MCP Server gives AI applications a standardized and secure interface to access authorized Xeams functions through APIs. - AI assistants can search emails, retrieve message content and attachments, validate email addresses, check delivery status and monitor server health. - The MCP Server is designed to let users interact with email through natural language instead of manual searches and complex navigation. - Xeams Web Access lets users open their mailbox directly from a browser without separate installation. - XWA lets users manage email preferences, spam filtering settings, white lists, black lists, out-of-office notifications and end-to-end encryption settings from one interface. - Build 6448 includes a redesigned web interface with side navigation. - Build 6448 adds the ability to pause and resume outbound mail queues. - Build 6448 includes Smart Search that identifies queries as email addresses, IP addresses, subjects or message content. - Build 6448 adds email search by attachment name, such as SalesReport.pdf. - Build 6448 expands Email Campaign management, including edits to previously uploaded recipient lists. - Build 6448 allows non-admin users to create and manage email campaigns. - Build 6448 adds tools to view and remove blocked IP addresses from the Tools menu. - Build 6448 enhances SMTP relay monitoring with statistics for authorized relay IP addresses and hostnames. - Build 6448 adds configurable alerts when email volume from authorized relay sources exceeds set thresholds. - Build 6448 adds the ability to import DKIM keys from external systems. - Xeams supports AI-powered spam, phishing, ransomware and malware protection. - Xeams supports DMARC, SPF, DKIM, ARC and MTA-STS. - Xeams includes end-to-end email encryption, secure attachment protection, archiving, clustering, high availability and enterprise reporting tools. - Xeams also supports OAuth 2.0 and SSL certificate-based authentication for SMTP relay.

Between the lines: - The AI features suggest Synametrics is positioning Xeams as more than an email security stack and more like an operational control layer for AI-enabled workflows. - The Microsoft IIS SMTP alternative pitch targets organizations that need to keep legacy devices and applications running while moving to modern authentication standards. - The broader feature set signals an effort to keep administrators inside Xeams for both user-facing mail access and backend management.

What's next: - Xeams 10.3 is now available for download. - More information is available in the changelog. - Organizations using legacy SMTP relay tools may evaluate Xeams as a replacement or migration path. - Synametrics will likely continue expanding AI and automation features as enterprise email operations become more workflow-driven.

The bottom line: - Xeams 10.3 is a meaningful upgrade for organizations that want AI-assisted email management, a modern web client and stronger control over secure mail delivery.
