[Discuss] Postfix ailiaes question

[johnhall2.0 at gmail.com (John Hall)]

I think we need the messages and logs not the paraphrased messages and logs
otherwise how is anyone going to see something you did not see?
I'm presuming you don't have se-linux or apparmor on?
What user is running the mail daemon?  Does it 100% spawn processes under
this same user or does it use the mail users' permissions for anything?
I can't remember. I think for all it's internals , for what is
automatically managed it definitely is the mail daemon user but it just
might not do that for some features that are intended for user directories
using patterns.
