The data you are comparing is a String, so I would just use strings.  Symbols
have their uses, but they are not supposed to take over the world.

David Naseby identified a speed difference, but that will only affect you if
you are doing a lot of comparisons.

Therefore, I recommend:

  case header.lowercase
  when "to", "cc", "bcc"
    ...
  when "from"
    ...
  end

Good luck.
