How to send an email with attachments using SmtpClient.SendAsync?

Question

I am using a service component through ASP.NET MVC. I would like to send the email in a asynchronous way to let the user do other stuff without having to wait for the sendin

I have tried your function and it works even for email with in memory attachments. But here are some remarks:

• What type of attachments did you try to send ? Exe ?
• Are both sender and receiver on the same email server ?
• You should “catch” exception and not just swallow it, than you will get more info about your problem.

• What does the exception says ?

• Does it work whan you use Send instead of SendAsync ? You are using 'using' clause and closing Stream before email is sent.
