There is no .NET framework support for IMAP. 
You'll need to use some 3rd party component.

Try <a href="https://www.limilabs.com/mail" rel="noreferrer">https://www.limilabs.com/mail</a>, 
it's very affordable and easy to use, it also supports SSL:

<pre><code>using(Imap imap = new Imap())
{
 imap.ConnectSSL("imap.company.com");
 imap.Login("user", "password");

 imap.SelectInbox();
 List&lt;long&gt; uids = imap.SearchFlag(Flag.Unseen);
 foreach (long uid in uids)
 {
 string eml = imap.GetMessageByUID(uid);
 IMail message = new MailBuilder()
 .CreateFromEml(eml);

 Console.WriteLine(message.Subject);
 Console.WriteLine(message.TextDataString);
 }
 imap.Close(true);
}
</code></pre>

I've been searching for an IMAP solution for a while now, and after trying quite a few, I'm going with <a href="https://github.com/andyedinborough/aenetmail">AE.Net.Mail</a>.

You can download the code by going to the Code tab and click the small 'Download' icon. As the author does not provide any pre-built downloads, you must compile it yourself. (I believe you can get it through NuGet though). There is no longer a .dll in the bin/ folder.

There is no documentation, which I consider a downside, but I was able to whip this up by looking at the source code (yay for open source!) and using Intellisense. The below code connects specifically to Gmail's IMAP server:

<pre><code>// Connect to the IMAP server. The 'true' parameter specifies to use SSL
// which is important (for Gmail at least)
ImapClient ic = new ImapClient("imap.gmail.com", "name@gmail.com", "pass",
 ImapClient.AuthMethods.Login, 993, true);
// Select a mailbox. Case-insensitive
ic.SelectMailbox("INBOX");
Console.WriteLine(ic.GetMessageCount());
// Get the first *11* messages. 0 is the first message;
// and it also includes the 10th message, which is really the eleventh ;)
// MailMessage represents, well, a message in your mailbox
MailMessage[] mm = ic.GetMessages(0, 10);
foreach (MailMessage m in mm)
{
 Console.WriteLine(m.Subject);
}
// Probably wiser to use a using statement
ic.Dispose();
</code></pre>

Make sure you checkout the <a href="https://github.com/andyedinborough/aenetmail">Github</a> page for the newest version and some better code examples.

In the hope that it will be useful to some, you may want to check out my go
at it:

<a href="https://github.com/smiley22/S22.Imap">S22.Imap</a>

While there are a couple of good and well-documented IMAP libraries for .NET
available, none of them are free for personal, let alone commercial use...and
I was just not all that satisfied with the mostly abandoned free alternatives
I found.

S22.Imap supports IMAP IDLE notifications as well as SSL and partial message
fetching. I have put some effort into producing <a href="http://smiley22.github.com/S22.Imap/Documentation/">documentation</a> and keeping
it up to date, because with the projects I found, documentation was often sparse
or non-existent.

Feel free to give it a try and let me know if you run into any issues!

Is there a built-in method to access an Imap server (with SSL) in C# or is there a good free library?

在C#中有没有内置的方法来访问Imap服务器(使用SSL)，或者有没有很好的免费库？
