## MDaemon 25.5.0 - 2025-09-09

### SPECIAL CONSIDERATIONS

- [28444] MDaemon 25.5 requires Windows 10, Server 2012, or newer.

### CHANGES AND NEW FEATURES

#### MDAEMON SERVER

- [27782] VBR has been deprecated and removed.
- [28621] MDaemon logs the From header address when rejecting a message because it does not match AUTH credentials.
- [28655] A new SSL/TLS option has been added: "Automatically detect and activate newer certificates". When enabled, MDaemon will check at startup and during its daily maintenance for newer versions of each active certificate for MDaemon, Webmail, and Remote Administration. If another certificate on the system expires later, is for the same hostname, and includes all alternative hostnames, MDaemon will automatically switch to it and restart the affected servers. This option is enabled by default.
- [10357] A new "Send As Permissions" screen has been added at Security | Security Manager | Sender Authentication that lets you configure what other email addresses accounts are allowed to send mail as when the credential matching requirements on the SMTP Authentication screen are enabled. Normally (when not exempt), accounts can only send mail from their own email address or aliases. A wildcard address like *@example.com can be used for the account to set addresses that all accounts in the domain can send as. Wildcards can also be used in the send as addresses to allow an account to send as any address that matches the pattern.
- [28006] The minimum length of strong passwords can now be set higher than 15 if non-reversible password encryption is enabled.
- [28117] Added legend to the Location Screening dialog that explains what the symbols mean.
- [27967] The Automatic Gateway Creation screen is not displayed in the GUI if it's not being used.
- [25423] Updated DMARC Public suffix file URL to the latest recommended URL.
- [28777] The "Block except SMTP, disable authentication" label on the Location Screening dialog has been changed to "Prevent authentication". It still does the same thing, we're just trying to make it easier to understand.
- [28822] The LDAP port has been removed from the Ports dialog. It can still be configured on the LDAP dialog.
- [22966] The MultiPOP "Do not download messages larger than" setting now allows 5 digits.
- [20947] The feature to disable accounts after X days of inactivity will now disable accounts that have never been accessed if it's been more than X days since they were created.
- [23130] The \MDaemon\PEM\ folder is now included in the config file backup system.

#### REMOTE ADMINISTRATION

- [28658] Added the Active Directory Group input field to the Group Properties page at Main | Groups | Edit

#### WEBMAIL

- [28551] Added options in Publish Schedule to require or hide the phone, address, and notes fields on the appointment scheduling view.
- [28660] Webmail includes an account's Send As Addresses as possible From addresses when composing. This is enabled by default. It can be disabled by editing \MDaemon\WorldClient\Domains.ini and setting [Default:UserDefaults] ComposeWithSendAsAddresses=No. The display name for each address can be set in the Pro theme if AllowEditAliasDisplayName is enabled.
- [28661] Pro theme - Added a search input for the Copy/Move dialog
- [28521] Webmail now saves user session information when it is shutdown through MDaemon, and loads it on start up.

- [28722] Pro theme - Added leading zeros to the dates that are not using the autoformatted feature
- [28679] Changed the Two Factor Auth email verification code email to include a text/plain part, so that it's consumable for cellphone provider SMS gateways

#### WEB CONFERENCE SERVER

- [21211] Added a Web Conference Server which can be connected to through MDaemon Webmail Pro theme. Configuration settings are in Remote Administration at Main | Web Conference Server. Added the Web Conference button in Pro theme in the top nav bar that opens a Web Conference page and connects the user to the Web Conference Server through Webmail. The Web Conference Server requires Windows 10 / Server 2016 or newer.
