MimeProxy is a module built for parsing MIME messages. Since MIME is not a communication protocol in itself, the MIME proxy cannot be used on its own. It can only inspect data received from a protocol proxy (e.g.: a HTTP proxy, POP3 proxy, etc. that stacks the MimeProxy). MimeProxy reads the data received from the other proxy and handles message headers and bodies if there are any. If the message conforms to the RFC standard it is accepted, otherwise the content is rejected. It is also possible to stack a further proxy into the Mime module (e.g.: a virus filtering module).
