Instead of signing in to Webmail with their MDaemon email address and password, users can use the **Sign in with SSO** button to sign in to an OIDC identity provider. MDaemon Webmail will then sign them in to the MDaemon account associated with their identity provider account. *Note: Requires app setup via your identity provider’s management interface. Please see the MDaemon release notes for more information.* *![MDaemon-Webmail-Single-Sign-On\_WebReady](https://blog.mdaemon.com/hs-fs/hubfs/MDaemon-Webmail-Single-Sign-On_WebReady.png?width=1920&height=1075&name=MDaemon-Webmail-Single-Sign-On_WebReady.png)* ### Web Conferencing Improvements – Record, Transfer Files & More! **MDaemon’s web conferencing feature has been improved significantly:** - Web conferences can now be recorded - The web conferencing feature now supports file sharing among meeting attendees - Join links are now created for external users when they are invited to a conference #### Rejected Inbound Messages Report To help administrators more easily troubleshoot email delivery issues, a Rejected Inbound messages report has been added to MDaemon Remote Administration. This report provides a graphical listing of all messages that were rejected within a designated time frame, along with the reason each was rejected (spam, virus, over quota, RFC non-compliance, and more). ![Screenshot of the MDaemon Reports console showing a "Rejected Inbound Messages" chart over the last 24 hours, broken down by rejection reason](https://blog.mdaemon.com/hs-fs/hubfs/MDaemon-Rejected-Messages-Report_WebReady.jpg?width=711&height=398&name=MDaemon-Rejected-Messages-Report_WebReady.jpg) #### Statistics Log Search We’ve added a sortable and searchable page for the MDaemon Statistics log. This allows administrators to search the Statistics logs for inbound and/or outbound sessions based on date or date range, message delivery result (accepted, quarantined, rejected), reject/quarantine reason (spam, virus, SPF rejected, etc.), sender, recipient, and subject. ![MDaemon-Statistics-Log-Search\_WebReady](https://blog.mdaemon.com/hs-fs/hubfs/MDaemon-Statistics-Log-Search_WebReady.png?width=1920&height=1075&name=MDaemon-Statistics-Log-Search_WebReady.png) #### Other Improvements MDaemon •    Content Filter - Added restricted attachment exclusions by sender and recipient •    [MDMigrator](https://knowledge.mdaemon.com/migrating-from-microsoft-exchange-to-mdaemon)- Added search filter to mailbox selection page to filter by name or email address  •    LetsEncrypt - Allow ECDSA certificates to be used in production •    Trusted Hosts - Renamed the "Trusted Hosts" dialog to "Trusted Domains". The values here are compared to the domain in MAIL FROM commands, not the FQDN in HELO/EHLO commands. Use with care, as trusted domains can bypass various security features. ##### MDaemon Webmail •    Pro theme - Added the ability to set the nickname of a favorited folder For a complete list of new features and updates, please see the [MDaemon release notes](http://files.mdaemon.com/MDaemon/Release/RelNotes_en.html).
