    }

### FlagsClear

The FlagsClear notification is emitted when all flags are removed from a message.

This includes `\Deleted`, `\Seen` and `\Flagged`, and as such are, in part, the counter-parts to MessageTrash, MessageRead, and FlagsSet.

    }

### FlagsSet

The FlagsSet notification is emitted when flags are set on a message, but not including the `\Deleted` and `\Seen` flags, which emit MessageTrash and MessageRead event notifications respectively.

### QuotaChange

Note

This event may be followed by a QuotaWithin event notification, if the quota change leads the quota root to allow more resources than currently in use.

### QuotaExceed

The `user` parameter in the event notification is the user to whom the quota applies, that is being exceeded, otherwise known as the owner of the Personal Namespace.

Note

Quota being exceeded on shared folders cannot include an “owner” for the quota root.

Footnotes for QuotaWithin

[1] | A `QuotaWithin` event follows a `MailboxDelete` event if the mailbox deleted resides inside a quota root, and lowers the resources used to below the existing quota thresholds.

[2] | A `QuotaWithin` event follows a `MessageExpunge` event if the messages purged reside inside a quota root, and amount to a number or size that lowers the amount of resources used to below the existing quota thresholds.

[3]

A `QuotaWithin` event follows a `MessageMove` event if the source folder of the messages moved resides inside a quota root, and the target folder to which the messages have been moved does not reside within the same quota root, and the number or size of the messages moves lowers the amount of resources used in the quota root for the source folder of the messages to below the existing quota thresholds.

[4] | A `QuotaWithin` event follows a `QuotaChange` event if the quota change raised the threshold on the amount of resources used within the quota root to a level higher than the existing amount of resources used.

### CalendarAlarm

The `CalendarAlarm` event occurs when a calendar event triggers an alarm.

### ApplePushService

While Cyrus supports the Apple Push Service, Apple has only licensed Apple Push for mail to a couple of large mail providers: FastMail and Yahoo. If you own an OS X Server license, you also get a key for personal use. But it’s not a supported option for third party developers at this time.

The `ApplePushService` event occurs when
