The maildirsize file is double counting messages when moving them from folder to folder when "maildir_copy_with_hardlinks = no":

1024000000000S 99337571 19370 14010590 2 <--- moved from subfolder to subfolder -7005295 -1 14010590 2 <--- moved from subfolder to INBOX -7005295 -1 14010590 2 <--- moved from INBOX to subfolder -7005295 -1 14010590 2 <--- moved from subfolder to subfolder -7005295 -1

When I change "maildir_copy_with_hardlinks" to "yes", this problem only occurs when moving in and out of the INBOX, but not when moving from subfolder to subfolder:

7005295 1 <--- moved from subfolder to subfolder -7005295 -1 14010590 2 <--- moved from subfolder to INBOX -7005295 -1 14010590 2 <--- moved from INBOX to subfolder -7005295 -1 7005295 1 <--- moved from subfolder to subfolder -7005295 -1
