Detailed Description

A TCP/IP socket for the Simple Mail Transfer Protocol.

When acting as a client, the procedure is to make the connection to a remote server, then to send a message using the following procedure:


      PSMTPSocket mail("mailserver");
      if (mail.IsOpen()) {
        mail.BeginMessage("Me@here.com.au", "Fred@somwhere.com");
        mail.Write(myMessage);
        if (!mail.EndMessage())
          PError << "Mail send failed." << endl;
      }
      else
         PError << "Mail conection failed." << endl;

Constructor & Destructor Documentation

PSMTPClient::PSMTPClient ( )

Create a TCP/IP SMPTP 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.

PSMTPClient::~PSMTPClient ( )

Destroy the channel object. This will close the channel and as a client, QUIT from remote SMTP server.

Member Function Documentation

virtual BOOL PSMTPClient::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.

BOOL PSMTPClient::LogIn	(	const PString &	username,
		const PString &	password
	)

Log into the SMTP server using the mailbox and access codes specified. Login is actually attempted only if the server supports SASL authentication and a common method is found

Returns:: TRUE if logged in.

Parameters:

username	User name on remote system.
password	Password for user name.

BOOL PSMTPClient::BeginMessage	(	const PString &	from,
		const PString &	to,
		BOOL	eightBitMIME = `FALSE`
	)

Begin transmission of a message using the SMTP socket as a client. This negotiates with the remote server and establishes the protocol state for data transmission. The usual Write() or stream commands may then be used to transmit the data itself.

Returns:: TRUE if message was handled, FALSE if an error occurs.

Parameters:

from	User name of sender.
to	User name of recipient.
eightBitMIME	Mesage will be 8 bit MIME.

BOOL PSMTPClient::BeginMessage	(	const PString &	from,
		const PStringList &	toList,
		BOOL	eightBitMIME = `FALSE`
	)

Parameters:

from	User name of sender.
toList	List of user names of recipients.
eightBitMIME	Mesage will be 8 bit MIME.

BOOL PSMTPClient::EndMessage ( )

End transmission of a message using the SMTP socket as a client.

Returns:: TRUE if message was accepted by remote server, FALSE if an error occurs.

BOOL PSMTPClient::OnOpen ( ) [protected, virtual]

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.
