Delayed Email Setting Option

Hi,
   I am using your eM Client from few months without any issues, I wan to know where the option for Sending “Delayed Email”, Below are the details of the version and license i am using.

Version : 7.0.26687
License : Free

When you are composing your email if you select menu > message > delayed send. This will open a window so you can select the date and time you want the email to be sent.

Thank you 

Can you Cancel the send before the specified time?

Can you set ALL emails to delay 30 or so seconds and allow for cancellation prior to the time?
