Mail: show most recent messages at the top
I would like to have the most recent messages of a conversation displayed at the top. In "View", I have enabled the option "Organise by conversation" and chose to sort by date with the newest message on top. This works fine for the left-hand column where the emails are grouped by conversation, i.e. they appear chronologically sorted by date. However, in the conversation window on the right, emails appear unsorted and in seemingly arbitrary order. In "Preferences/Viewing", I have ticked both "Include related messages" and "Show most recent message at the top", but this doesn't seem to do anything. I have also tried "Mailbox/Rebuild" on every mailbox, but unfortunately that doesn't seem to fix the problem either.
Any ideas on how to fix this issue?
