Send, receive, edit, sign/verify and encrypt/decrypt email messages in any .NET application or service. 

Imap Bitmap Imap Component

Easily manage and download messages from any IMAP4 server. A local object model makes remote mail management easy, with no knowledge of IMAP4 commands required!

  • Multithreaded design 
    • Commands from multiple worker threads are sychonized and "queued up" (the CommandCount property indicates how many commands are in the queue)
    • Idle() will block (and raise the Update event asynchronously) until a command is sent on another thread, automatically cancelling the IDLE command and allowing Idle() to return
    • Imap Client sample demonstrates advanced multithreaded use
  • Authentication support: CRAM-MD5, GSSAPI and NTLM (with single-sign-on), LOGIN, PLAIN, clear-text
  • Select secure (SSL 2.0, SSL 3.0, PCT, TLS) or unencrypted TCP communications.
  • There is no need to understand the IMAP4 protocol. Use the Imap component's intuitively named properties and methods and the appropriate command is sent to the server.
  • Server-side mailboxes are represented as Mailbox objects. Used to change properties or get details about a mailbox.
  • Multiple mailboxes are represented as a MailboxCollection. Used to manage nested mailboxes.
  • Server-side messages are represented as ImapMessage objects. Used to change message flags or get message data.
  • Authenticate and decrypt Secure MIME (S/MIME) messages.
  • Flexible message retrieval enables the developer to retrieve an entire message, headers only, attachments only, or any part desired.
  • Imap.Connection property exposes the TCP connection used to send data. Use this object to get connection-level information, or log all data passing through the connection.
  • Other events include Progress (raised when a message is transferring), StateChanged (raised when the state of the connection has changed), and Update (raised when the selected Mailbox has been updated with a new message or a message has been deleted by another user).
