Previous versions of OS X had a dropdown menu under Viewing in Mail Preferences that allowed you to choose the type of heading or no heading at all when viewing an email. The drop down menu is still there but now there is only one choice available: "headers". I can find no mention of this issue on any Apple forums. Maybe no one else uses it? Or am I the only one with this issue? Would appreciate any suggestions for a fix. I often save emails as PDFs and prefer not to have header info showing.
