Retrieving attachments from an email account with .NET.

Question

I want the free library for .NET to receive attachments from an account (for example, gMail or others) via imap4 (optional) and save them in a folder.

Ideally, this will allow me to get a list of them and download only some of them (filtering by extension, name and / or size) and be free.

I already did this with a trial version of EAGetMail , but for what I am trying to buy an unlimited version of this library is not quite suitable (I did not know that this functionality itself was one of those who had a limited time).

--- [edit - Higuchi] ---

I am using the following code:

Dim cl As New Pop3Client()
        cl.UserName = "[e-mail]"
        cl.Password = "mypassword"
        cl.ServerName = "pop.gmail.com"
        cl.AuthenticateMode = Pop3AuthenticateMode.Pop
        cl.Ssl = False
        cl.Authenticate() //takes a while, but passes even if there a wrong password

        Dim mg As Pop3Message = cl.GetMessage(1) //gives me an exception: Message = "Pop3 connection is closed"

UPDATE: setting the port to 995 gives me a "Response TimeOut" exception
