how do I add smart folders

I want to add a Smart Folder for “Today’s Mail.” Is there a way to add a custom Smart Folder in emClient in the same way I could add a custom search in Outlook?

Try to create a Search folder - it should help.

Is there a generic “Today” variable that will adjust as dates change ? Currently the variable is changed to the physical date for that day so that if the rule is created on 2013-04-30 the rule will stay that day for all other future dates and not adjust to the current date.

No, this is not implemented yet.
