I think Akonadi maildir resource puts Inotify watches on all directories 
to recognize changes there. Back then I did place some mails manually 
there and Akonadi picked it up immediately.

If you also use Baloo and have lots of subfolders, maybe Baloo has 
consumed all inotify watches up to the low kernel default limit and then 
you may need to raise it, like this:

merkaba:~> cat /etc/sysctl.d/inotify.conf 
# martin at merkaba:~> find -type d | wc -l
# 34515
#
# merkaba:/proc/sys/fs/inotify> cat max_user_watches 
# 8192

fs.inotify.max_user_watches = 200000

Basically inotify needs a watch for every folder to monitor, also every 
sub folder.

Ciao,
