Use a seguinte função para chamar a caixa postal padrão:

Exemplo de chamada:

procedure TForm1.Button1Click(Sender: TObject);
var
mail: TStringList;
begin
mail := TStringList.Create;
try
mail.values[´to´] := ´Receiver-Email@test.xyz´;
mail.values[´subject´] := ´Hello´;
mail.values[´body´] := ´blah´;
mail.values[´body´] := ´blah´;
mail.values[´attachment0´] := ´C:\Test.txt´;
// mail.values[´attachment1´]:=´C:\Test2.txt´;
sendEMail(Application.Handle, mail);
finally
mail.Free;
end;
end;
