My guess would be that the mail message has opened the file, but doesn't close it until it get's disposed. The System.Web.MailMessage doesn't provide any way to explicitly do that.
try the System.Net.Mail API. System.Net.Mail.MailMessage has a dispose method, this will assure you that any resources used by the mail message will be released. The System.Web.Mail API recommends using the other newer API. Also, it is not explicitly stated in the documentation, but normally method that have "Async" in the name are synchronous. So that leads me to believe SmtpMail.Send() method is synchronous, therefore the sending of the message it complete when the method returns, you shouldn't need the Thread.Sleep().
