DNS audit results above came from public DNS. Everything in this panel comes only from files or text you supply.

Nothing supplied here is fetched, uploaded, stored, or added to your DNS score. Analysis happens locally in this browser and is discarded on reload. See Privacy.

MTA-STS policy

Paste the body of mta-sts.txt or choose a text file. Maximum 64 KiB.

BIMI SVG logo

Paste the SVG source or choose an SVG file. Maximum 32 KiB. The logo is inspected, never displayed.

BIMI checks cover security rejections and named SVG Tiny PS diagnostics; they are not full RNC-schema certification or a guarantee that a mailbox provider will display the logo.
