About AuthEmailTest.com
AuthEmailTest.com tests what actually happens when your mail system sends a message to this receiving server. DNS-only checks are useful, but they cannot show the real connecting IP, HELO name, envelope sender, header From address, DKIM signature domains, DMARC alignment, or spam filter scoring seen during SMTP delivery.
SPF
SPF checks whether the connecting SMTP server is authorised to send for the envelope sender domain. This live test records the IP and HELO used for the message and evaluates SPF from the receiver side.
DKIM
DKIM uses a cryptographic signature in the message and a public key in DNS. This test inspects the DKIM-Signature headers, selector, signing domain, and verification result on the message that arrived.
DMARC
DMARC checks whether SPF or DKIM passes in alignment with the visible From domain. This is often where apparently separate SPF and DKIM details meet, especially when a provider sends with a different envelope sender or signing domain.
Spam Filtering
After the message is accepted, AuthEmailTest.com runs Rspamd and SpamAssassin scans and reports their scores, actions, and main rules. These checks are useful diagnostics, but filtering decisions vary between providers and gateways.
How The Test Works
You enter the address you intend to send from, complete verification, and receive a temporary address under incoming.authemailtest.com. That address is valid for a short time and accepts one message only. After the message is received, the result page shows the SMTP session, authentication outcome, and spam-filter scan results.
