ImapProxy is a module built for parsing requests and responses of the IMAP protocol. It reads all the REQUESTs at the client side, parses them and - if the local security policy permits - sends them to the server one-by-one. When the RESPONSEs arrive they are parsed by the proxy and sent to the client one by one if the local security policy permits it. Simple greeting rewriting is supported to hide the version of the server. ImapProxy also implements the NAMESPACE, RLIST and RLSUB commands and the LOGIN authentication method. Other authentication methods are not supported and are denied (the proxy does not send them to the policy level).
