    1024-bit DKIM key
    DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (1024 bits), selector1 (1024 bits), mta (1024 bits). Rotate to a 2048-bit key.

  • !
    Key in test mode
    DKIM · These keys have t=y, so receivers treat DKIM failures as a test: mail. Remove t=y once DKIM works.
