Mail servers for t-online.de
t-online.de publishes 4 MX records. Senders deliver to the lowest-priority host first, mx01.t-online.de, and fall back down the list if it does not answer.
Who runs the mail
The hosts match the pattern of an unrecognised provider. The mail hosts do not match a known provider pattern, so the domain is probably self-hosted or on a smaller provider. Catch-all behaviour varies from server to server, which is exactly why a mailbox-level probe, not the MX record, decides whether an address exists.
What this means for verification
An address at t-online.de passes the free checks (syntax, MX, lists), so the API goes on to the mailbox-level SMTP handshake, which ends before any message is sent. The result is deliverable, risky, or undeliverable with a reason field that names the evidence.
