AuthEmailTest.comInbound Email Authentication Test

Having problems sending email, checking a new mail system, or just making sure your configuration is healthy?

AuthEmailTest.com gives you a temporary inbound address to send a message to and then shows how this receiving server saw the message you sent.

It checks the real connecting IP, HELO name, envelope sender, header From address, DKIM signatures, SPF result, DMARC alignment, and spam filter analysis.
