Yes, my filesystems are mounted with relatime set.  It's not much use
if mailbox.mbox.add() doesn't play by the rules though.

mbox has several advantages over maildir (for me anyway):-

    It allows easy removal of empty mailboxes (in my case by the MUA)

    It's much easier to search

    It's easier to move things around

    It doesn't have silly ways of delimiting directories as do some
    maildir implementations.
