C# sent Email Visualization Problem

[erPanita]

Hello.. I'm using the C# class System.Net.Mail.MailMessagein order to send Emails in HTML Format. The HTML body comes from a Crystal Report converted to HTML Format 40 through the Crystal Class from Visual Studio .NET

The problem is that the e-mail looks just fine in e-mail clients such as Microsoft Outlook, howeverer, if i try to forward the e-mail it looks all bad, all aligned to the left and it looses all format. The same thing happens when i send the email to servers such as G-mail or hotmail.

The e-mail has embedded images, and this is part of the code used to send the e-mails

                System.Net.Mail.MailMessage mensajeEmail = new System.Net.Mail.MailMessage();
                System.Net.NetworkCredential cred = new System.Net.NetworkCredential(_user, _password);
//                mensajeEmail.IsBodyHtml = true; // Aceptamos HTML
                foreach(string _destinatario in _para)
                {
                    if (_destinatario != null)
                    {
                        mensajeEmail.To.Add(_destinatario);
                    }
                }
                if (_cc != null)
                {
                    foreach (string _copia in _cc)
                    {
                        if (_copia != null)
                        {
                            mensajeEmail.CC.Add(_copia);
                        }
                    }
                }
                if (_bcc != null)
                {
                    foreach (string _copiaOculta in _bcc)
                    {
                        if (_copiaOculta != null)
                        {
                            mensajeEmail.Bcc.Add(_copiaOculta);
                        }
                    }
                }
 
                mensajeEmail.Subject = _subject;
                mensajeEmail.From = new System.Net.Mail.MailAddress(_fromMail, _from);
                string _bodyMessage = _mensaje;
                int _secImagen = 0;
//se cambia cada coincidencia de "images/nombre de la imagen" por un consecutivo cid:imagenN para luego asociarlas.
                foreach (string _imagenes in images)
                {
                    string _imagen = _imagenes.Replace(_filePath + "\\", "");
                    _bodyMessage = _bodyMessage.Replace("images/" + _imagen, "cid:imagen" + _secImagen.ToString());
                    _secImagen++;
                }
 
                System.Net.Mail.AlternateView html = 
                    System.Net.Mail.AlternateView.CreateAlternateViewFromString(_bodyMessage, System.Text.Encoding.UTF8 , "text/html");
 
 
//se agrega cada imagen al mensaje como un recurso enlazado
                _secImagen = 0;
                foreach (string _imagenes in images)
                {
                    System.Net.Mail.LinkedResource imagen = new System.Net.Mail.LinkedResource(_imagenes);
                    imagen.ContentId = "imagen" + _secImagen.ToString();
                    _secImagen++;
                    html.LinkedResources.Add(imagen);
                }
                mensajeEmail.AlternateViews.Add(html);
                mensajeEmail.IsBodyHtml = true;
 
//                mensajeEmail.Body = _mensaje;
                System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient(_serverName); //seleccionamos nuestro servidor smtp
                smtp.UseDefaultCredentials = false;
//                smtp.EnableSsl = true;
                smtp.Credentials = cred; //asignamos la credencial
//                mensajeEmail.Attachments.Add(archivoAnexo); //se agregan los archivos anexos
                smtp.Send(mensajeEmail); // enviamos
            }
            catch(Exception ex)
            {
                System.Console.WriteLine(ex.Message.ToString() + " -***- " + ex.Source.ToString()
                    + " -***- " + ex.Source.ToString());
//                System.Console.ReadLine();
                return false;
            }
            return true;
 

BTW I'm using embedded images in this e-mail.

Those anyone knows how to make the e-mails look fine on any client? I'm really stuck and desperate in this... I have tried different types of encodings and nothing seems to work.

Thanks

Email clients are like browsers, you can't absolutely control what happens after you serve your code to the client. You can't even ensure that everyone accepts html emails. The simpler the code the more likely it will look the same in the widest range of email clients. Suggest you choose the cleanest format and test in a range of clients. Probably easiest to work backwards once you have the email you want than adjust the code...
