Comment 3 for bug 978584

The "network inet stream" is already in the packaged profile - in other words: it doesn't count ;-)

The problem is caused by a change in the logging format. See the upstream bugreport https://bugs.launchpad.net/apparmor/+bug/800826
(just tested - logprof works if you delete the "lport=143" part)

Independent from that - are there other dovecot-related profiles that need an inet6 rule added? I'd guess usr.lib.dovecot.managesieve-login could need it - at least it already contains an inet rule.
