Proxy testing in container( chown failed /var/dovecot/login)

[Marc Roos]

I am testing a bit with the proxy, and trying to run dovecot as a normal 
user. (with cap bind_service). I was wondering what the minimum 
configuration is for running like a proxy. 

I am now getting issues like unable to chown on /var/dovecot/login, but 
I do not need this in such a setup do I?

passdb {
  driver = static
  args = proxy=y host=192.168.11.10 nopassword=y
}
