Postmaster mail copies

All mails sent to the special Postmaster addresses are saved into the MIREKA_HOME/postmaster directory. They are sent to their assigned destination as well. There are two types of postmaster addresses. In the first form, no domain is specified. This is always accepted. In the second form, domain part is also specified. These are only accepted if the domain is a local domain. This feature is useful for debugging. The saved file shows the content of the message before any processing. The mails are saved even if an error occurs later in the processing chain, e.g. the back-end server cannot be connected in proxy mode.

You may need to clear the directory occasionally.
