Mail - SMTP Add authentication

[RoboIntern]

Hi Marco,

Hmm, I wonder are you attaching a file or something else? I've just tried on my side with an SMTP account and it didn't lock it, even after a second run.

Below is how I handle the file lock by the way:

                    emailClient.Send(message);

                    foreach (Attachment attachment in message.Attachments)
                    {
                        attachment.Dispose();
                    }
