Kernel increases the limit immediately, so you don't need to do anything
else. There's no need to even restart Dovecot (although existing IMAP
processes that failed to use inotify before won't be using it until the
client reconnects).

When IMAP client uses IDLE command, Dovecot can't use inotify to notify
the client immediately after new message has been received.
