Schedule sending mail

This feature allows you to send mail out at a later time rather than immediately upon clicking Send button.

NB: The module is not currently included into WebMail Lite, but you can add this module as described here.
The feature requires setting a cronjob (see below).

To enable the feature, edit data/settings/modules/MailScheduledMessages.config.json configuration file and set "Disabled" to false there. Once that's done, you'll get an additional "Schedule sending" dropdown option at "Send" button:

Upon selecting this option, you'll get a popup asking when you wish the message to be sent out. You can configure predefined message scheduling options by editing "PredefinedSchedule" configuration file setting.

You'll notice an additional Scheduled folder created in your account, and a message will be stored there scheduled for delivery at a specified date and time. You can cancel sending message out from there:

IMPORTANT:
For this feature to work, modules/MailScheduledMessages/Crons/send-scheduled-messages.php script needs to be run every 5 minutes. On Linux, that's typically done via cronjob, run crontab -e and append the following line there:

*/5 * * * * php /var/www/webmail/modules/MailScheduledMessages/Crons/send-scheduled-messages.php

Make sure you supply the correct path for your WebMail Lite installation.

On Windows, you can use built-in scheduler, or a crontab alternative.
