I'm looking for a simple function where any email I "send" will automatically be delayed for a certain amount of time, say 15 minutes, before it is actually sent in the event I'd like to recall it. I'd like to be able to set it as a default for all emails - don't want to have to indicate this desire each time I send an email. Seems like there are products out there to do this for PCs via Outlook, but I cannot find anything for Mac email. Anyone know of anything?
