Good news, no warnings or errors were found.

We detected some possible recommendations for you to consider. No penalties were given for these, but resolving them can give you a higher DNS score.

  • No SPF records were found. SPF records limit which IPs are allowed to send mail from this domain. Even if this domain doesn't send e-mails, you should set up SPF to confirm it will never send e-mail, to prevent spoofing.
  • No DMARC records have been found. Consider configuring DMARC for improved e-mail authentication.
  • No IPv6 record has been found on the zone apex (e18.ph.tum.de). Consider enabling IPv6 in the infrastructure by adding an AAAA record on this domain.

Good news, we detected the following achievements in your DNS configuration. Each of these checks has increased your DNS Spy score.

  • Multiple MX records found.
  • MX records with different priorities found (main + fall-back mailservers).
  • The MX record for "e18.ph.tum.de" has a long TTL (1h+).
  • The MX records points to multiple mailservers.
  • The NS records have a long TTL (1h+).
  • Your SOA serial number follows the best practice YYYYMMDDxx format.
  • Found a root (apex) DNS record.
  • Found a www DNS record.
