### SPECIAL CONSIDERATIONS

[16456] Hosted email options with MDaemon Private Cloud are now available. To learn more, please visit: https://mdaemon.com/pages/mdaemon-email-msp.

### CHANGES AND NEW FEATURES

#### WEBMAIL

- [5759] Changed the server to no longer load unsubscribed folders when HideUnsubscribedFolders=Yes for the user. The unsubscribed folders will be loaded for the Settings | Folders page.

- [27500] SMTP Server - To prevent inbound SMTP smuggling, MDaemon now requires message data to end with <CRLF>.<CRLF>. Previously, it would allow <LF>.<LF>. To disable this, edit \MDaemon\App\MDaemon.ini and set [Special] SMTPRequireCRLFdotCRLF=No.

## MDaemon 23.5.0 - September 26, 2023

### CHANGES AND NEW FEATURES

#### WEBMAIL

- [26455] Added a Public Schedule option, so that users can allow others to schedule a meeting.
- [20285] Added support for WebAuthn (formerly FIDO U2F) as a passwordless authentication method or as a Two Factor Auth method.
- [26890] Pro theme - Added AI based functionality to summarize a message, suggest a reply, and improve an email being composed by the user. This feature submits message data to openai.com, so please be cautious about the information you submit.
  Webmail's AI message features are disabled by default for all domains. They can be enabled by checking "Enable AI message features" in the MD GUI at Setup | Webmail & IM Services | Webmail | Settings and the Domain Manager's Webmail screen, or in MDRA at Main | Webmail Settings | Settings and Main | Domain Manager | Webmail Settings.
  Webmail's AI message features are disabled per user by default. You can enable them as part of a Group controlled by an Account Template or per user. The Domain setting takes precedence over the user setting. If it is disabled on the Domain level, then enabling it on the Group or user level does nothing. If the feature is disabled, the WCAPI will return a 404 Not Found error.
- [26604] Made some visual updates to Pro theme.
- [26612] Added a warning message on the login screen when the caps lock is turned on.

- [19656] The Location Screening option "SMTP connections are accepted but authentication is blocked" is now per country instead of global. Blocking SMTP connections prevents your server from receiving mail from a country.
