Authorization page for yandex mail PHP?

Question

PHP

Good day, tell me how to create an authorization page in PHP with a transition to corporate mail. Today we have a website and corporate mail through the company's domain on Yandex, and an automatic transition for authorization by mail (mail.domen.ru) is also configured. Would you like to make a page with a company logo with a form for entering a login and password, and the next step would be to open the mailbox itself? Does anyone have a ready made version?

Answer 1

It's impossible. You need to log in exactly in the form of Yandex. You are using a free service, so you can't.

Answer 2

Maybe Yandex corporate mail has the possibility of branding?

Answer 3

I know it's "crutty", but what? You can make a redirect, though it will be without branding. It is possible through frame.
