NAME Net::IMAP::Server - A single-threaded multiplexing IMAP server implementation, using Net::Server::Coro. SYNOPSIS use Net::IMAP::Server; Net::IMAP::Server->new( port => 193, ssl_port => 993, auth_class => "Your::Auth::Class", model_class => "Your::Model::Class", user => "nobody", group => "nobody", )->run; DESCRIPTION This model provides a complete implementation of the "RFC 3501" specification, along with several IMAP4rev1 extensions. It provides separation of the mailbox and message store from the client interaction loop. Note that, following RFC suggestions, login is not allowed except under a either SSL or TLS. Thus, you are required to have a certs/ directory under the current working directory, containing files server-cert.pem and "server-key.pem". Failure to do so will cause the server to fail to start. INTERFACE The primary method of using this module is to supply your own model and auth classes, which inherit from Net::IMAP::Server::DefaultModel and Net::IMAP::Server::DefaultAuth. This allows you to back your messages from arbitrary data sources, or provide your own authorization backend. For the most part, the implementation of the IMAP components should be opaque. METHODS new PARAMHASH Creates a new IMAP server object. This doesn't even bind to the sockets; it merely initializes the object. It will "die" if it cannot find the appropriate certificate files. Valid arguments to "new" include: port The port to bind to. Defaults to port 1430. ssl_port The port to open an SSL listener on; by default, this is disabled, and any true value enables it. auth_class The name of the class which implements authentication. This must be a subclass of Net::IMAP::Server::DefaultAuth. model_class The name of the class which implements the model backend. This must be a subclass of Net::IMAP::Server::DefaultModel. connection_class On rare occasions, you may wish to subclass the connection class; this class must be a subclass of Net::IMAP::Server::Connection. user The name or ID of the user that the server should run as; this defaults to the current user. Note that privileges are dropped after binding to the port and reading the certificates, so escalated privileges should not be needed. Running as your "nobody" user or equivilent is suggested. group The name or ID of the group that the server should run as; see "user", above. poll_every How often the current mailbox should be polled, in seconds; defaults to 0, which means it will be polled after every client command. unauth_commands The number of commands before unauthenticated users are disconnected. The default is 10; set to zero to disable. unauth_idle How long, in seconds, to wait before disconnecting idle connections which have not authenticated yet. The default is 5 minutes; set to zero to disable (which is not advised). auth_idle How long, in seconds, to wait before disconnecting authentiated connections. By RFC specification, this must be longer than 30 minutes. The default is an hour; set to zero to disable. run Starts the server; this method shouldn't be expected to return. Within this method, $Net::IMAP::Server::Server is set to the object that this was called on; thus, all IMAP objecst have a way of referring to the server -- and though "connection", whatever parts of the IMAP internals they need. process_request Accepts a client connection; this method is needed for the Net::Server infrastructure. DESTROY On destruction, ensure that we close all client connections and listening sockets. connections Returns an arrayref of Net::IMAP::Server::Connection objects which are currently connected to the server. connection Returns the currently active Net::IMAP::Server::Connection object, if there is one. This is determined by examining the current coroutine. concurrent_mailbox_connections [MAILBOX] This can be called as either a class method or an instance method; it returns the set of connections which are concurrently connected to the given mailbox object (which defaults to the current connection's selected mailbox) concurrent_user_connections [USER] This can be called as either a class method or an instance method; it returns the set of connections whose "user" in Net::IMAP::Server::DefaultAuth is the same as the given USER (which defaults to the current connection's user) capability Returns the "CAPABILITY" string for the server. This string my be modified by the connection before being sent to the client (see "capability" in Net::IMAP::Server::Connection). id Returns a hash of properties to be conveyed to the client, should they ask the server's identity.
