[neomutt-users] Old (O) messages shown as new (N) in index

[Mihai Lazarescu]

I'm using NeoMutt 20180716 with maildir folders on Fedora 28.

Flag Old (O) is shown as New (N) whenever I reopen the 
folder.  I.e., I cannot make permanent the "O" flag: 
http://www.mutt.org/doc/manual/#tab-msg-status-flags

Coming from mutt, I would expect that after setting Old flag 
(<set-flag>O) and syncing (<sync-mailbox>), when I reopen the 
folder to see that the message preserved the flag "O" (old) 
in index.  But I see it flagged as "N" (new) instead.

Is this behaviour intended?

Thanks,
Mihai
