Questions about tum.de
Technical University of Munich email questions, answered from this data
Every answer comes from the numbers on this page, 90 days to November 6, 2026.
What email domain does Technical University of Munich use?
tum.de. Its MX record points to postrelay2.lrz.de, with SPF published and DMARC published, checked October 27, 2026.
What is the most common tum.de email format?
[email protected]: 81–85% (95% range 77–89%) of the 295+ distinct tum.de addresses mailfloss verified in the 90 days to November 6, 2026. Next: [email protected] at 5% and "one word, not a recognised name" at 5%.
Is tum.de a catch-all domain?
No. In mailfloss's checks (latest October 27, 2026), tum.de mostly rejected addresses that do not exist, so it is not a catch-all domain. Because tum.de mostly rejects mailboxes that do not exist, a permanent (5xx) "mailbox does not exist" or "account disabled" answer from it is reliable, and those addresses can come off your list; a 4xx answer is temporary, so retry it. An accepted answer is strong but not certain evidence that the mailbox exists. A full inbox or a busy mailbox is temporary, so recheck those later.
Do tum.de addresses bounce?
Of mailfloss's tum.de verifications in the 90 days to November 6, 2026, 82–86% were accepted, 10% got no clear answer and 6% were rejected.
How do I find or check an email address at tum.de?
Build it from the person's name in the most common format, [email protected], then verify it before you send: mailfloss asks the tum.de mail server about that exact address and reports what it answered. Because tum.de is not a catch-all domain, a clear answer means what it says. Verify one now.
Does Technical University of Munich use Google Workspace or Microsoft 365?
Microsoft 365, the mailbox provider on mailfloss's record. Its published MX record is not one mailfloss recognises, so whether a security gateway sits in front of it is not known.
