What I want is something like a 10-minute-mail inside my gmail account!!!

Yahoo Mail does this. You can make a specific new address and then delete it when you're done. https://help.yahoo.com/kb/mail/SLN3523.html

Fastmail also does this. They have hundreds of domains you can use for disposable accounts.

I just use mailinator. No charge, no hassle, you don't have to set it up first. Half the time I don't even end up checking it. So far I don't really have a use case for plus addressing.

Yes, that's on my wishlist too!
