Splitting hairs as to the exact moment the envelope went into the mailbox is not helpful. You know the refund is on its way if the IRS site says so. It will come by first class mail without tracking. There are variations in the speed with which the mail is sorted and delivered by postal workers and your own mailman. Just watch your mailbox and do not throw away any mail without opening it first to make sure it is not junk mail.
