Detailed Description

A TCP/IP socket for the Post Office Protocol version 3.

When acting as a client, the procedure is to make the connection to a remote server, then to retrieve a message using the following procedure: PPOP3Client mail; if (mail.Connect("popserver")) { if (mail.LogIn("Me", "password")) { if (mail.GetMessageCount() > 0) { PUnsignedArray sizes = mail.GetMessageSizes(); for (PINDEX i = 0; i < sizes.GetSize(); i++) { if (mail.BeginMessage(i+1)) mail.Read(myMessage, sizes[i]); else PError << "Error getting mail message." << endl; } } else PError << "No mail messages." << endl; } else PError << "Mail log in failed." << endl; } else PError << "Mail conection failed." << endl;

Member Enumeration Documentation

enum PPOP3Client::LoginOptions

Enumerator
AllowUserPass	Allow the use of the plain old USER/PASS if APOP or SASL are not available.
UseSASL	Use SASL if the AUTH command is supported by the server.
AllowClearTextSASL	Allow LOGIN and PLAIN mechanisms to be used.

Constructor & Destructor Documentation

PPOP3Client::PPOP3Client

(

)

Create a TCP/IP POP3 protocol socket channel.

The parameterless form creates an unopened socket, the form with the address parameter makes a connection to a remote system, opening the socket. The form with the socket parameter opens the socket to an incoming call from a "listening" socket.

PPOP3Client::~PPOP3Client

(

)

Destroy the channel object.

This will close the channel and as a client, QUIT from remote POP3 server.

Member Function Documentation

PBoolean PPOP3Client::BeginMessage

(

PINDEX

messageNumber

)

Parameters

messageNumber

Number of message to retrieve. This is an integer from 1 to the maximum number of messages available.

virtual PBoolean PPOP3Client::Close ( )

virtual

Close the socket, and if connected as a client, QUITs from server.

Returns

true if the channel was closed and the QUIT accepted by the server.

Reimplemented from PIndirectChannel.

PBoolean PPOP3Client::DeleteMessage

(

PINDEX

messageNumber

)

Delete the message specified from the mail box.

Returns

Array of strings continaing message headers.

int PPOP3Client::GetMessageCount

(

)

Get a count of the number of messages in the mail box.

Returns

Number of messages in mailbox or -1 if an error occurred.

PStringArray PPOP3Client::GetMessageHeaders

(

)

Get an array of a strings representing the standard internet message headers of each of the messages in the mail box.

Note that the remote server may not support this function, in which case an empty array will be returned.

Returns

Array of strings continaing message headers.

PUnsignedArray PPOP3Client::GetMessageSizes

(

)

Get an array of a integers representing the sizes of each of the messages in the mail box.

Returns

Array of integers representing the size of each message.

PBoolean PPOP3Client::LogIn	(	const PString &	username,
		const PString &	password,
		int	options = AllowUserPass
	)

Log into the POP server using the mailbox and access codes specified.

Returns

true if logged in.

Parameters

username	User name on remote system.
password	Password for user name.
options	See LoginOptions above

PBoolean PPOP3Client::OnOpen ( )

protectedvirtual

This callback is executed when the Open() function is called with open channels.

It may be used by descendent channels to do any handshaking required by the protocol that channel embodies.

The default behaviour is to simply return true.

Returns

Returns true if the protocol handshaking is successful.

Reimplemented from PIndirectChannel.
