Our take

MailX exposes a practical hosted toolbox for email deliverability checks: SPF, DKIM, DMARC, BIMI, blacklist checks, SMTP/IMAP connectivity, DNS lookups, and record generation. The public server card is detailed and the tools are mostly read-only, with generators clearly not marked as read-only. This is a remote service, so auditability depends on the operator rather than source code.
