MailBee IMAP4 Component

MailBee IMAP4 Component

Fast and flexible COM object that enables your application or ASP page to search, receive, parse and manage email over IMAP4 protocol
MailBee Objects bundle includes SMTP, POP3, IMAP, S/MIME components.

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, 32/64 bit.

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

IMAP4 Object reference...

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
