Is github.com disposable?
github.com is not on the disposable list and is not a free provider, so addresses at it belong to an organisation rather than to personal accounts.
About the domain
Its mail is handled by Microsoft 365. Public registry data (RDAP) shows github.com was registered on 2007-10-09, so it is about 18 years old.
How Spaw treats addresses at github.com
For github.com, verification runs the whole pipeline: syntax, live MX, the open lists, and then the SMTP handshake with the mail host, with no message ever transmitted. Each verdict carries a machine-readable reason.
