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;
When acting as a server, a descendant class would be created to override
at least the LookUpName() and HandleMessage() functions.
Other functions may be overridden for further enhancement to the sockets
capabilities, but these two will give a basic SMTP server functionality.
The server socket thread would continuously call the
ProcessMessage() function until it returns FALSE. This will then
call the appropriate virtual function on parsing the SMTP protocol.

Constructor & Destructor Documentation
PSMTPServer::PSMTPServer |
( |
|
) |
|
|
|
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. |
Member Function Documentation
|
Determine if a user for this domain may be on the local system, or should be forwarded.
- Returns:
- Result of forward check operation.
|
virtual BOOL PSMTPServer::HandleMessage |
( |
PCharArray & |
buffer, |
|
|
BOOL |
starting, |
|
|
BOOL |
completed |
|
) |
[virtual] |
|
|
Handle a received message. The buffer parameter contains the partial or complete message received, depending on the completed parameter.
The default behaviour is to simply return FALSE;
- Returns:
- TRUE if message was handled, FALSE if an error occurs.
|
|
Look up a name in the context of the SMTP server.
The default bahaviour simply returns FALSE.
- Returns:
- Result of name look up operation.

virtual BOOL PSMTPServer::OnMIMEData |
( |
PCharArray & |
buffer, |
|
|
BOOL & |
completed |
|
) |
[protected, virtual] |
|
|
Read an eight bit MIME message that is being received by the socket. The MIME message is terminated by the CR/LF/./CR/LF sequence.
The default behaviour is to read the data into the buffer parameter until either the end of the message or when the messageBufferSize bytes have been read.
- Returns:
- TRUE if partial message received, FALSE if the end of the data was received.
|
virtual void PSMTPServer::OnNOOP |
( |
|
) |
[protected, virtual] |
|
BOOL PSMTPServer::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.
- Returns:
- Returns TRUE if the protocol handshaking is successful.

virtual BOOL PSMTPServer::OnTextData |
( |
PCharArray & |
buffer, |
|
|
BOOL & |
completed |
|
) |
[protected, virtual] |
|
|
Read a standard text message that is being received by the socket. The text message is terminated by a line with a '.' character alone.
The default behaviour is to read the data into the buffer parameter until either the end of the message or when the messageBufferSize bytes have been read.
- Returns:
- TRUE if partial message received, FALSE if the end of the data was received.
|
virtual void PSMTPServer::OnTURN |
( |
|
) |
[protected, virtual] |
|
virtual BOOL PSMTPServer::OnUnknown |
( |
const PCaselessString & |
command |
) |
[protected, virtual] |
|
|
Handle an unknown command.
- Returns:
- TRUE if more processing may be done, FALSE if the ProcessCommand() function is to return FALSE.
|
virtual void PSMTPServer::OnVRFY |
( |
const PCaselessString & |
name |
) |
[protected, virtual] |
|
BOOL PSMTPServer::ProcessCommand |
( |
|
) |
|
|
|
Process commands, dispatching to the appropriate virtual function. This is used when the socket is acting as a server.
- Returns:
- TRUE if more processing may be done, FALSE if the QUIT command was received or the OnUnknown() function returns FALSE.
