A virtual-domain-supporting POP3 server.

Method authenticateUserAPOP Authenticate against a user against a virtual domain.

Inherited from VirtualPOP3:

Instance Variable service The email service that created this server. This must be set by the service. (type: MailService)
Instance Variable domainSpecifier The character to use to split an email address into local-part and domain. The default is '@'. (type: bytes)
Method authenticateUserPASS Perform authentication for a username/password login.
Method lookupDomain Check whether a domain is among the virtual domains supported by the mail service.

Inherited from POP3 (via VirtualPOP3):

Instance Variable portal A portal for authentication. (type: Portal)
Instance Variable factory A server factory which provides an interface for querying capabilities of the server. (type: IServerFactory provider)
Instance Variable timeOut The number of seconds to wait for a command from the client before disconnecting. (type: int)
Instance Variable schedule A callable that arranges for an iterator to be cooperatively iterated over along with all other iterators which have been passed to it such that runtime is divided between all of them. It returns a deferred which fires when the iterator finishes. (type: callable that takes interator and returns Deferred)
Instance Variable magic An APOP challenge. If not set, an APOP challenge string will be generated when a connection is made. (type: bytes or None)
Instance Variable mbox The mailbox for the authenticated user. (type: IMailbox provider)
Instance Variable state The state which indicates what type of messages are expected from the client. Valid states are 'COMMAND' and 'AUTH' (type: bytes)
Instance Variable blocked A list of blocked commands. While a response to a command is being generated by the server, other commands are blocked. When no command is outstanding, blocked is set to none. Otherwise, it contains a list of information about blocked commands. Each list entry consists of the command and the arguments to the command. (type: None or list of 2-tuple of (1) bytes (2) tuple of bytes)

Method _unblock Process as many blocked commands as possible.
Method _cbMailbox Complete successful authentication.
Method _ebMailbox Handle an expected authentication failure.
Method _ebUnexpected Handle an unexpected authentication failure.
Method _longOperation Stop timeouts and block further command processing while a long operation completes.
Method _coiterate Direct the output of an iterator to the transport and arrange for iteration to take place.
Method _getMessageFile Retrieve the size and contents of a message.

Inherited from LineOnlyReceiver (via VirtualPOP3, POP3):

Class Variable delimiter The line-ending delimiter to use. By default this is b'\r\n'.
Class Variable MAX_LENGTH The maximum length of a line to allow (If a sent line is longer than this, the connection is dropped). Default is 16384.
Method dataReceived Translates bytes into lines, and calls lineReceived.
Method sendLine Sends a line to the other end of the connection.
Method lineLengthExceeded Called when the maximum line length has been reached. Override if it needs to be dealt with in some special way.

Inherited from Protocol (via VirtualPOP3, POP3, LineOnlyReceiver):

Method logPrefix Return a prefix matching the class name, to identify log messages related to this protocol instance.

Inherited from BaseProtocol (via VirtualPOP3, POP3, LineOnlyReceiver, Protocol):

Method makeConnection Make a connection to a transport and a server.

Inherited from TimeoutMixin (via VirtualPOP3, POP3):

Method callLater Wrapper around reactor.callLater for test purpose.
Method resetTimeout Reset the timeout count down.
Method setTimeout Change the timeout period
Method timeoutConnection Called when the connection times out.
Method __timedOut Undocumented
def authenticateUserAPOP(self, user, digest):

Authenticate against a user against a virtual domain.

ParametersuserThe username.
digestThe digested password.
ReturnsA three-tuple like the one returned by IRealm.requestAvatar. The mailbox will be for the user given by user.
