t-mobile.de MX records
t-mobile.de publishes a single MX host, mailin.ng.telekom.net. With no backup host, a sender that can't reach it queues the message and retries until the server answers or the queue gives up.
t-mobile.de SPF record
t-mobile.de published no SPF record (no v=spf1 TXT at the apex) on 5 November 2026. Without one, receivers can't tell which servers may send as @t-mobile.de, so they lean on DKIM and the sending server's reputation instead (RFC 7208).
t-mobile.de DMARC policy
The record is v=DMARC1;p=none;rua=mailto:[email protected];ruf=mailto:[email protected];.
p=none only asks for reports; failing mail is delivered as normal.
Aggregate reports go to telekom.com, so the domain's owner sees who sends mail as @t-mobile.de.
Can you verify @t-mobile.de addresses?
Our checker treats @t-mobile.de like any domain: syntax, MX, disposable and role checks first, then a made-up address to rule out a catch-all, then your address at RCPT TO, disconnecting without sending. We have not published a test of how mailin.ng.telekom.net answers for @t-mobile.de, so we make no claim here about whether single mailboxes can be confirmed; each result carries its own reason.
Cleaning a list with these addresses
DNS tells you where mail goes, not whether one person's mailbox still exists. For a list, run the whole file through a verifier before you send: invalid rows come out, risky rows (catch-all, unknown, refused) go in their own segment, and valid rows are safe to mail.
