following code is what i modified(to work with 10.5.8) form the sample in order to send email independently using the smtp client described in Indy Mail server
following is from INDY smtpserver sample
procedure TForm1.btnServerOnClick(Sender: TObject);
begin
IdSMTPServer1.active := true;
end;
procedure TForm1.btnServerOffClick(Sender: TObject);
begin
IdSMTPServer1.active := false;
end;
procedure TForm1.IdSMTPServer1MailFrom(ASender: TIdSMTPServerContext;
const AAddress: string; AParams: TStrings; var VAction: TIdMailFromReply);
begin
// Here we are testing the MAIL FROM line sent to the server.
// MAIL FROM address comes in via AAddress. VAction sets the return action to the server.
// The following actions can be returned to the server:
{ mAccept, mReject }
// For now, we will just always allow the mail from address.
VAction := mAccept;
end;
procedure TForm1.IdSMTPServer1MsgReceive(ASender: TIdSMTPServerContext;
AMsg: TStream; var LAction: TIdDataReply);
var
LMsg : TIdMessage;
LStream : TFileStream;
begin
// When a message is received by the server, this event fires.
// The message data is made available in the AMsg : TStream.
// In this example, we will save it to a temporary file, and the load it using
// IdMessage and parse some header elements.
LStream := TFileStream.Create(ExtractFilePath(Application.exename) + 'test.eml', fmCreate);
Try
LStream.CopyFrom(AMsg, 0);
Finally
FreeAndNil(LStream);
End;
LMsg := TIdMessage.Create;
Try
LMsg.LoadFromFile(ExtractFilePath(Application.exename) + 'test.eml', False);
ToLabel.Caption := LMsg.Recipients.EMailAddresses;
FromLabel.Caption := LMsg.From.Text;
SubjectLabel.Caption := LMsg.Subject;
Memo1.Lines := LMsg.Body;
Finally
FreeAndNil(LMsg);
End;
end;
procedure TForm1.IdSMTPServer1UserLogin(ASender: TIdSMTPServerContext;
const AUsername, APassword: String; var VAuthenticated: Boolean);
begin
// This event is fired if a user attempts to login to the server
// Normally used to grant relay access to specific users etc.
VAuthenticated := True;
end;
procedure TForm1.IdSMTPServer1RcptTo(ASender: TIdSMTPServerContext;
const AAddress: string; AParams: TStrings; var VAction: TIdRCPToReply;
var VForward: string);
begin
VAction := rAddressOk;
end;
procedure TForm1.IdSMTPServer1Received(ASender: TIdSMTPServerContext;
var AReceived: string);
begin
//
end;
what do i have to add to this project to work as email sending server.
I haven't done many changes to the original sample(only for compatibility) as i can't understand most of the concepts behind how email is sent and received. please explain me how to make this code to send email to the destination(eg: someone@gmail.com) given in this question Indy Mail server (smtpclient),
To pass the email on to another system (Gmail in this case), use the TIdSMTPRelay
component, eg:
procedure TForm1.IdSMTPServer1RcptTo(ASender: TIdSMTPServerContext;
const AAddress: string; AParams: TStrings; var VAction: TIdRCPToReply;
var VForward: string);
begin
if (AAddress represents a user in your network) then
VAction := rAddressOk
else if (AAddress is outside of your network) then
VAction := rWillForward;
end;
procedure TForm1.IdSMTPServer1MsgReceive(ASender: TIdSMTPServerContext; AMsg: TStream; var LAction: TIdDataReply);
var
LMsg : TIdMessage;
LMsgClient: TIdMessageClient;
LStream : TFileStream;
LRelayRecipients: TIdEMailAddressList;
LRelay: TIdSMTPRelay;
I: Integer;
begin
// When a message is received by the server, this event fires.
// The message data is made available in the AMsg : TStream.
// In this example, we will save it to a temporary file, and load it using
// IdMessage to parse some header elements.
LStream := TFileStream.Create(ExtractFilePath(Application.exename) + 'test.eml', fmCreate);
Try
LStream.CopyFrom(AMsg, 0);
Finally
LStream.Free;
End;
AMsg.Position := 0;
LMsg := TIdMessage.Create;
Try
//LMsg.LoadFromFile(ExtractFilePath(Application.exename) + 'test.eml', False);
// Do not use the TIdMessage.LoadFrom...() methods here! The email
// data contained in the AMsg stream does not escape leading periods
// on lines of text. That escaping is only used when the email was
// transmitted over the socket, as a period character has special
// meaning to the SMTP protocol. TIdSMTPServer removes the escaping
// from the data before firing this event. However, the LoadFrom...()
// methods (which uses TIdMessageClient internally) require the
// data to be escaped! This is a known limitation in Indy's core
// architecture and will be addressed in Indy 11. Until then,
// use TIdMessageClient manually so the necessary escaping can be
// re-introduced into the data while it is being parsed...
LMsgClient := TIdMessageClient.Create(nil);
try
LMsgClient.IOHandler := TIdIOHandlerStreamMsg.Create(LMsgClient, AMsg);
with TIdIOHandlerStreamMsg(LMsgClient.IOHandler) do
begin
FreeStreams := False;
EscapeLines := True;
end;
LMsgClient.IOHandler.Open;
LMsgClient.ProcessMessage(LMsg, False);
finally
LMsgClient.Free;
end;
// process LMsg as needed...
// save the email for local users and forward it to other SMTP servers as needed...
LRelayRecipients := nil;
try
for I := 0 to ASender.RCPTList.Count-1 do
begin
if (ASender.RCPTList[I] represents a user in your network) then
begin
// save AMsg in the user's mailbox somewhere on the local
// machine/network where an POP3/IMAP4 client can retreive
// it from later...
end else
begin
if not Assigned(LRelayRecipients) then LRelayRecipients := TIdEMailAddressList.Create(nil);
LRelayRecipients.Add.Assign(ASender.RCPTList[I]);
end;
end;
if Assigned(LRelayRecipients) then
begin
LRelay := TIdSMTPRelay.Create(nil);
try
// you must supply the IP/Host of a DNS server that
// will be used for determining the SMTP server of
// each recipient domain...
LRelay.DNSServer := ...;
LRelay.Send(LMsg, LRelayRecipients);
finally
LRelay.Free;
end;
end;
finally
LRelayRecipients.Free;
end;
Finally
LMsg.Free;
End;
end;
