MailBee.NET IMAP is a high-performance memory-conservative .NET component for processing mails and folders on IMAP4 servers. The component can do everything the POP3 component does, and much more: download and manage folders, search, flag, upload, move, copy messages, download message envelopes or any specific parts or attributes of messages, etc.

MailBee.NET IMAP downloads messages in a batch, drastically improving performance.

MailBee.NET IMAP bundle includes a set of MIME objects such as MailMessage and Attachment which are used for e-mail parsing.

Written in 100% managed code, MailBee.NET IMAP only requires the .NET framework be installed on the computer.

MailBee.NET IMAP can be used in any .NET language including C# and VB.NET. Supported .NET frameworks include .NET 2.0/3.0/3.5/4.0.
