Frequently Asked Questions
Q: I don't see the icon. The character string such as Message-ID or DKIM-Signature is displayed.
A: This happens if the email does not have an X-Mailer or User-Agent header. Since Display Mail User Agent T identifies the MUA based on X-Mailer or User-Agent in principle, it cannot handle emails that do not have these email headers. Display the message source (☰ → View → Message Source or Ctrl + U) and check it.
