Using UTC allows easy log correlation with remote MTAs.

 The ``REAL_IP_HEADER`` (default: unset) and ``REAL_IP_FROM`` (default: unset) settings controls whether HTTP headers such as ``X-Forwarded-For`` or ``X-Real-IP`` should be trusted. The former should be the name of the HTTP header to extract the client IP address from and the later a comma separated list of IP addresses designing which proxies to trust. If you are using Mailu behind a reverse proxy, you should set both. Setting the former without the later introduces a security vulnerability allowing a potential attacker to spoof his source address.
