Currently, imapnotify substitutes %s in onNotify by a formatted mailbox name, i.e., the mailbox name is converted to lowercase and / is replaced by -. It would be great if imapnotify would support putting the mailbox name directly (without any reformatting; e.g., via %S) so that it can be used by the onNotify script to sync just that folder. Right now, this does not work for me because folder names are case sensitive and / needs to be kept.
