Receiving email and downloading attachment through a C# Application

I am trying to implement a WPF application which can receive the mails sent to a specific email address. The scenario is that, the user will send a PPT file as an attachment to a specific email address, and my WPF application will listen to this email and once it receives the email, it will download the attached file and saves it to the hard drive.

I looked a bit, but all I found was that the System.Net.Mail only supports sending emails through an application using System.Net.Mail.SmtpClient class. Can anyone suggest me how to do this in WPF and C#.

Thanks in advance!
