You are correct that it's due to the Apparmor profile not permitting
this. encfs is not supported by the stock profile. You have multiple
options to workaround this:
1) log elsewhere
2) add a rule to the local override file
(/etc/apparmor.d/local/usr.bin.msmtp)
3) disable the apparmor profile completely
I would recommend 2) as the safest option. Please see the NEWS file for
the full details but it should look like this (as root):
echo ' owner @{HOME}/orgd/msmtp.log wk,' \
>> /etc/apparmor.d/local/usr.bin.msmtp
apparmor_parser -R /etc/apparmor.d/usr.bin.msmtp
Then it should be able to log to the real backing file under
~vincent/orgd. Please let me know if the above still doesn't work.

Simon
