Title: How to connect and retrieve email to a POP3 account
Question: This post will demonstrate how to connect and retrieve mail from a POP3 account.
For the purpose of this demonstration we will need
a TIdPOP3 component and a TIdMessage component.
Answer:
procedure TForm1.Button2Click(Sender: TObject);
var
MsgCount : Integer;
i : Integer;
FMailMessage : TIdMessage;
begin
Memo1.Lines.Clear;
//The IdPop31 is on the form so it is constructing when the
//form is created and so is Memo1.
IdPOP31.Host := 'mypop3.example.com'; //Setting the HostName;
IdPOP31.Username := 'myusername';//Setting UserName;
IdPOP31.Password := 'mypassword';//Setting Password;
IdPOP31.Port := 110;//Setting Port;
try
IdPOP31.Connect();
//Getting the number of the messages that server has.
MsgCount := IdPOP31.CheckMessages;
for i:= 0 to Pred(MsgCount) do
begin
try
FMailMessage := TIdMessage.Create(nil);
IdPOP31.Retrieve(i,FMailMessage);
Memo1.Lines.Add('=================================================');
Memo1.Lines.Add(FMailMessage.From.Address);
Memo1.Lines.Add(FMailMessage.Recipients.EMailAddresses);
Memo1.Lines.Add(FMailMessage.Subject);
Memo1.Lines.Add(FMailMessage.Sender.Address);
Memo1.Lines.Add(FMailMessage.Body.Text);
Memo1.Lines.Add('=================================================');
finally
FMailMessage.Free;
end;
end;
finally
IdPOP31.Disconnect;
end;
end;
