Sorry, but the previous writer is partly wrong and partly right.
Apostrophes are used to designate possession. they are also used to show 'contractions'. For ex: /do not/ becomes don't. And /can not/ becomes can't.
Now for your qu about the mail: today's mail, or tomorrow's mail or yesterday's mail. All have the apostrophe before the /s/ because there is only one mail.
If you had two people's mail in your hand, you would say, "I have yesterdays' mails." The apostrophe comes AFTER the /s/ to indicate that more than one mail exists.
Ditto: 4 cats have 4 black tails
"Look at those cats! The cats' tails are black."
But if only one cat: "That cat's tail is black."
Bit confusing, but follows the rules of English grammar.

As the mail belongs to yesterday, its 'yesterday's'. The other version implies that there is more than one yesterday.

The correct way to write that would be Yesterdays' mail.
It's yesterdays' there for the apostophy is after the s.
Before the 's means (__) is. ie. That's mine= That IS mine
