Hi, since I upgraded from XUbuntu 15.04 to 15.10 I started to get a lot
of apparmor complains about dovecot. The complains were more or less
like this:

operation="connect" profile="/usr/lib/dovecot/auth" name="/run/dovecot/anvil-auth-penalty" comm="auth" requested_mask="wr" denied_mask="wr" fsuid=0 ouid=0

operation="signal" profile="/usr/sbin/dovecot" comm="dovecot" requested_mask="send" denied_mask="send" signal=int peer="/usr/lib/dovecot/auth"


To avoid them, I added some stuff to the /etc/apparmor.d/local directory, patch attached.
