MailBee IMAP4 enables developers to easily add IMAP capabilities to their Windows or classic ASP applications. The component supports message search and checking new/read/unread status (all of the above - without downloading entire messages or even message headers). All the basic features are fully supported as well - preview messages, download, parse and manage messages and mailboxes (folders). The component can be used in any ActiveX-aware language such as classic ASP, VB, Delphi, C++, etc.

This is ActiveX component. Looking for .NET version? See MailBee.NET IMAP.

The component supports a number of IMAP extensions like IDLE (instant notifications about new events like arrival of a new e-mail), XLIST and SPECIAL-USE (special folder flags like Drafts, Sent, Trash), SORT, MOVE, QUOTA.

With SSL support available at no additional cost, you can download e-mail from S/IMAP servers, such as Gmail.

With the help of MailBee S/MIME Component, encrypted or signed e-mails can be decrypted and verified.

Supports all Windows versions from 2000 to 2012, 32/64 bit.

No knowledge of IMAP4, SSL, MIME and S/MIME is required.

  • IMAP QUOTA now returns not only allocated but also occupied space in the mailbox (QuotaUsage property).
  • AddressDelimiter property to make it easier to split address strings into individual addresses.
  • Filename autogeneration for attachments without filenames. New FilenameAsIs property to get the original filename.
  • Samples now reside in My Documents instead of Program Files (eliminates UAC issues when opening sample projects).
  • Revised VB6 IMAP samples to support message sets.

MailMessage Object

  • Available in all MailBee Objects packages (POP3, SMTP, Objects). Used as a main unit POP3 retrieval and SMTP sending methods operate with
  • Because SMTP object composes messages using Message object, all composing functionality of SMTP object also applies to Message object
  • Includes collection of a message's attachments
  • Provides access to custom message headers through GetHeader method
  • Can be created explicitly through CreateObject and then saved to disk or sent by SMTP object
  • Any content can be loaded to RawBody property (such as content of message file or attachment with message inside)
  • RawBody operates symmetrically: when you set Message properties or call Message-affecting methods (such as AddAttachment), RawBody will reflect this changes next time you read it; when you load RawBody with new value, other Message properties such as BodyText are refreshed
  • No redundant refreshes on RawBody. If you sequentially change some Message properties, RawBody will be updated only when you read it, not after every changing Message properties
