Can an address at s5tgwsfh.psmscientific.com receive email?

The domain has mail servers configured, but this does not confirm that a particular mailbox exists or will accept email. Disposable inboxes are temporary, even when they can receive verification emails.

Should I block s5tgwsfh.psmscientific.com at signup?

If you need to reach the account holder later, or your product has a free tier, yes. Signups from disposable domains are rarely recoverable customers. If you only need a one-time confirmation, a challenge such as a phone number may be enough.

How do I block s5tgwsfh.psmscientific.com and other disposable domains?

Send the address to GET /email/{address}, or the domain to GET /domain/{domain}, and reject the signup when disposable is true. The response covers every domain in the dataset, including ones added today, so there is no list to maintain. The guide to blocking disposable email addresses has code samples.
