How to properly implement list-unsubscribe?

Question

PHP

Hello everyone, I'm currently trying to implement the ability to unsubscribe from the mailing list using the list-unsubscribe header. Now the header looks like this

'List-Unsubscribe: <mailto:[email protected]?subject=unsubscribe>, <http://www.my.site/mail/unsubscribe/' . $this->_recipients . '/' . $type . '>'

A corresponding letter is sent to the [email protected] mail, but the action on the www.my.site/mail/unsubscribe/... link does not occur, the required email is not deleted from the database.
Or have I somehow misunderstood this technology?

Googled RFC www.faqs.org/rfcs/rfc2369.html As far as I understand, only the first possible method can be performed. Try to swap the link and mail, if it comes only to the site, then I'm right.
