Thunderbird Mailbox Alert

Mailbox Alert (via Genbeta) is a add-on for the popular mail client Thunderbird that adds the ability to define alerts for mail folders in Thunderbird. Alerts can be messages, sounds or commands. The default functionality in Thunderbird allows to define one sound or notification that will be displayed when new mail arrives which does include spam mail. With the Mailbox Alert extension it would be possible to only enable alerts for specific folders that contain important mails and ignore the spam folder.

Mailbox Alert does provide a better customization of the sound and notification alerts plus adds a complete new function to the alerts. The ability to start commands when a new mail arrives in a certain mail folder is excellent. The commands have to point to a file on the system but can contain parameters. I did not test if batch files are supported but I assume they are, why should not they ?

One possible scenario to make use of this new function would be to run a script that would move attachments to a network drive whenever a mail with attachments would arrive in a specific folder.

Defining notifications and sound alerts is pretty straightforward and does not really need any explanation. One nice feature are the global preferences that define how and where the Notification alert appears on the screen and how it reacts to a left-click. The available options are to close the popup or open the message.
