How to mark addresses

If you want to make sure you're sending an email from or to people at a specific domain — for example, if I want to make sure I'm sending from my imore.com address to my colleagues at imore.com, I can have iOS mark (i.e. highlight) those addresses.

  2. Tap Mail. You may have to scroll a little to find it.
