I ran dovecot-core 1:2.2.9-1ubuntu2.1 with apparmor-profiles
2.8.95~2430-0ubuntu5.3 and didn't get any errors in mail.log or
complaints from apparmor.

Title:
  dovecot/apparmor: profile not found

Bug description:
  [impact]

  This bug prevents dovecot users from using the apparmor policies shipped
  in the apparmor-profiles package without significant modifications.

  [steps to reproduce]

  1) install and setup dovecot and confirm that it's functioning as
     expected
  2) install the apparmor-profiles package
  3) restart dovecot to ensure apparmor policies are being applied
  4) if this bug has been addressed, dovecot should start successfully
     without generating apparmor rejections

  [regression potential]

  The change in the patch for this bug updates the dovecot policy to
  match the most recent apparmor release (2.9.2). These add missing
  policies, restructure a few things to common abstractions, and grant
  additional permissions. Any regressions related to this patch would
  be strictly limited to the policy for dovecot.

  [original description]

  I'm on Ubuntu 14.04 LTS. Since last week I get these messages:

  [11468.257576] type=1400 audit(1395659127.103:38560): apparmor="ALLOWED" operation="connect" profile="/usr/lib/dovecot/imap-login" name="/run/dovecot/config" pid=30971 comm="imap-login" requested_mask="rw" denied_mask="rw" fsuid=0 ouid=0

  When I then start dovecot I get these in mail.log:

  Mar 24 08:42:52 polly dovecot: master: Dovecot v2.2.9 starting up (core dumps disabled)

  Mar 24 08:55:42 polly dovecot: master: Error: service(imap-login): command startup failed, throttling for 2 secs

  I tried to purge and reinstall apparmor(-profiles) but that didn't fix
  this issue. I did a aa-disable dovecot and now the errors are gone.
