SMTP and IMAP server library for .NET

Question

Does anyone know a good SMTP/IMAP server library for C#?

I only found some long abandoned projects.

Only SERVER SIDE libraries, please

Answer 1

For SMTP, there's System.Net.Mail. For IMAP, I don't know. But once you fetch the email from the server, you'll want to parse it. The MIME parsing is the hard part. For that, I use, and recommend, SharpMimeTools.
