Works as advertised.
I noticed this warining:
Warning: fd limit (ulimit -n) is lower than required under max. load (1024 < 4096), because of service auth { client_limit }
What does exactly means?
The server we are talking about is my home server, a CentOS/64 with a dozen of mailboxes.
The fd limit is the maximum number of concurrently open file descriptors per process. It can be configured on a per-user basis. You can check the actual value running 'ulimit -n'. It can be increased up to the value set in /proc/sys/fs/file-max. You can set it editing /etc/security/limits.conf. What the above comment means is that under max load the auth service could need up to 4096 file descriptors open, that's more than the default in most linux systems (1024).
However, in your case with just a dozen of mailboxes I don't think you'll need to change it.
