MonitorWare Agent 26.11 is the latest monthly Patch + Feature Drop. It adds Microsoft 365 application OAuth for the Mail action and manual hostname mappings, and corrects TLS forwarding, SMTP reception, file output, Event Log monitoring, and configuration safety.
Send mail through Microsoft 365
The Mail action can send mail through Microsoft 365 using application-based OAuth authentication. The setting is available in the Configuration Client and in the User Interface, and a test mail can check the settings. SMTP LOGIN credentials are protected in diagnostic output and authentication failure reports, and encrypted mail verifies the destination. HTTPS probes also verify destination certificates and identities.
Map hostnames and IP addresses
General settings can define hostname and IP address mappings. The mappings are available in the Configuration Client and in the User Interface.
Safer forwarding, files, and configuration
The Syslog Listener rejects malformed message headers. The RELP Listener does not acknowledge records that could not be processed and handles diagnostic output safely. SETP handles malformed, empty, or deeply nested messages safely. The SMTP Listener limits incoming message size and reception time and does not accumulate memory across connections. The Event Log Monitor preserves the first event after a subscription resumes. The File action keeps dynamic output paths within their configured directories and writes queued data more efficiently. File rotation starts recovery before new events are processed, so pending rotated files can be recovered after service startup. TLS and DTLS forwarding verify destination certificates and identities, and stalled TLS forwarding no longer blocks shutdown indefinitely. Remote configuration rejects invalid HTTPS certificates and insecure redirects. Registry configuration detects the default license file more reliably when the license path is empty and no separate data directory is configured. When a listening socket cannot be opened, diagnostics include possible owners. The Configuration Client and the User Interface do not save a partial configuration after loading fails, and they preserve existing settings when a selective import fails. The Syslog action can set the TLS send progress timeout. The User Interface dashboard displays content in the selected language, and SMTP LOGIN username validation is corrected.
The User Interface remains in preview. It is available for production use with appropriate care and review; the Configuration Client remains fully supported.
We recommend keeping MonitorWare Agent on the latest Patch + Feature Drop to benefit from current maintenance and product improvements. Your licence remains valid for releases in its calendar year; Upgrade Insurance provides entitlement to later calendar years and their monthly Patch + Feature Drops.
