There's plenty of such solutions, both selfhosted and otherwise. of course as soon as your domain is listed on disposable email lists, you'll be denylisted from many sites but fortunately enough usually the sites who care about who you are are the least interesting ones, and it's still possible to register in many places using disposable inboxes EDIT: I should also mention most disposable email domains get added to the denylist after much use/abuse. By multiplying the domains/IPs serving disposable mailboxes, we greatly reduce the chance of being listed at all.
