Autorespond with headers

  • This service connects to an IMAP e-mail server and looks for e-mail that are unread/unseen in the Inbox
  • A new e-mail is created with the body of the e-mail being the header of the original inbound e-mail.
  • The e-mail is sent back (auto responds) to the original sender

Use case: Someone troubleshooting e-mail flow is able to determine if there are SPAM, SPF, DKIM, DMARC issues with their e-mail flow.
