      Description

      According to RFC341, the "MIME-Version" header must have MIME in caps.

      Some picky spam filters like rspamd add high scores to simple mistakes like this,
      increasing the likely hood the message is considered spam.

      I've seen this happen on version 2.5.0 but it is probably also present on older versions.

       

      Attached is a patch that fixes it for me, patch was rather simple as there was only one accordance of "Mime-Version" to be found.
