LumiSoft ee - works great  fairly easy  Compiles with  NET 4 0   Here are the required links to their lib and examples  Downloads Main   http   www lumisoft ee lsWWW Download Downloads   Code Examples   are located here      lsWWW Download Downloads Examples    NET   are located here      lsWWW Download Downloads Net   I am putting a SIMPLE sample up using their lib on codeplex  IMAPClientLumiSoft codeplex com    You must get their libraries directly from their site  I am not including them because I don t maintain their code nor do I have any rights to the code   Go to the links above and download it directly  I set LumiSoft project properties in my VS2010 to build all of it in  NET 4 0 which it did with no errors  Their samples are fairly complex and maybe even overly tight coding when just an example  Although I expect that these are aimed at advanced level developers in general   Their project worked with minor tweaks  The tweaks  Their IMAP Client Winform example is set in the project properties as  Release  which prevents VS from breaking on debug points   You must use the solution  Configuration Manager  to set the project to  Active Debug   for breakpoints to work  Their examples use anonymous methods for event handlers which is great tight coding    not real good as a teaching tool  My project uses  named  event method handlers so you can set breakpoints inside the handlers   However theirs is an excellent way to handle inline code   They might have used the newer Lambda methods available since  NET 3 0 but did not and I didn t try to convert them   From their samples I simplified the IMAP client to bare minimum

As the author of the above project i can say that yes it does support SSL    I am currently working on a new version of the library that will be completely asynchronous to increase the speed with which it can interact with IMAP servers    That code  while not complete  can be downloaded  along with the original synchronous library  which also supports SSL   from the code plex site linked to above

There is no  NET framework support for IMAP  You ll need to use some 3rd party component   Try Mail dll email component  it s very affordable and easy to use  it also supports SSL   using Imap imap   new Imap          imap ConnectSSL  imap company com        imap Login  user    password         imap SelectInbox        List lt long gt  uids   imap Search 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 Text             imap Close true       Please note that this is a commercial product I ve created   You can download it here  https   www limilabs com mail

I d recommend looking at MailKit as it is probably the most robust mail library out there and it s Open Source  MIT    One of the awesome things about MailKit is that all network APIs are cancelable  something I haven t seen available in any other IMAP library    It s also the only library that I know of that supports threading of messages   using System  using System Net  using System Threading   using MailKit Net Imap  using MailKit Search  using MailKit  using MimeKit   namespace TestClient       class Program               public static void Main  string   args                        using  var client   new ImapClient                       using  var cancel   new CancellationTokenSource                           client Connect   imap gmail com   993  true  cancel Token                           If you want to disable an authentication mechanism                         you can do so by removing the mechanism like this                      client AuthenticationMechanisms Remove   XOAUTH                         client Authenticate   joey    password   cancel Token                           The Inbox folder is always available                        var inbox   client Inbox                      inbox Open  FolderAccess ReadOnly  cancel Token                        Console WriteLine   Total messages   0    inbox Count                       Console WriteLine   Recent messages   0    inbox Recent                           download each message based on the message index                     for  int i   0  i  lt  inbox Count  i                              var message   inbox GetMessage  i  cancel Token                           Console WriteLine   Subject   0    message Subject                                                 let s try searching for some messages                        var query   SearchQuery DeliveredAfter  DateTime Parse   2013-01-12                             And  SearchQuery SubjectContains   MailKit                             And  SearchQuery Seen                        foreach  var uid in inbox Search  query  cancel Token                             var message   inbox GetMessage  uid  cancel Token                           Console WriteLine    match   0    1    uid  message Subject                                              client Disconnect  true  cancel Token

Lumisoft net has both IMAP client and server code that you can use    I ve used it to download email from Gmail  The object model isn t the best  but it is workable  and seems to be rather flexible and stable   Here is the partial result of my spike to use it  It fetches the first 10 headers with envelopes  and then fetches the full message   using  var client   new IMAP Client          client Connect  hostname   port   useSsl       client Authenticate  username   password       client SelectFolder  INBOX         var sequence   new IMAP SequenceSet        sequence Parse  0 10        var fetchItems   client FetchMessages sequence  IMAP FetchItem Flags Envelope   IMAP FetchItlags UID                                          false  true       foreach  var fetchItem in fetchItems                Console Out WriteLine  message UID    0    fetchItem UID           Console Out WriteLine  message Envelope From    0    fetchItem Envelope From           Console Out WriteLine  message Envelope To    0    fetchItem Envelope To           Console Out WriteLine  message Envelope Subject    0    fetchItem Envelope Subject           Console Out WriteLine  message Envelope MessageID    0    fetchItem Envelope MessageID             Console Out WriteLine  Fetching bodies        foreach  var fetchItem in client FetchMessages sequence  IMAP FetchItem Flags All  false  true                             var email   LumiSoft Net Mail Mail Message ParseFromByte fetchItem MessageData                        Console Out WriteLine  email BodyText    0    email BodyText

Cross posted from the other similar question  See what happens when they get so similar   I ve been searching for an IMAP solution for a while now  and after trying quite a few  I m going with AE Net Mail   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      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      I m not affiliated with this library or anything  but I ve found it very fast and stable
