MailBee Objects Features

POP3 Object

Supports secure authentication methods (including OAuth 2.0, APOP, NTLM, GSSAPI/NTLM, GSSAPI/Kerberos, Integrated Windows Authentication)
Supports Office 365, Gmail, and other providers.
Can retrieve all messages as a collection, retrieve only headers for each message, headers + part of message body
Can retrieve any single particular message or its headers
Can detect total message count in the mailbox, total size of all messages and sizes of every message. All of above does not require messages or headers retrieval
Automatically parses retrieved messages and headers (decoding from base64/quoted-printable/uue, converting data from local charset to Unicode, etc.)
Automatically creates plain-text version of HTML formatted message if plain version is not available in the message itself
Can determine whether a message contains attachments when downloading message headers only
Can delete messages from POP3 server
Supports logging POP3 session into the file
Can execute user-specified commands (SendCommand method)
Ping method allows you to implement "keep connection alive" function in your applications
Supports event mechanism to track retrieval progress (and abort retrieval if needed)
Supports message UIDs (unique-ids). This greatly simplifies programming task of detecting new mails, and dramatically decreases amount of data to be received from server for this purpose
Full and automatic support for Unicode and UTF-8. Supports international headers, attachment names, bodies, etc

IMAP4 Object

Supports Office 365, Gmail, and other providers.
Retrieves entire message, message header, message header and part of message body, message envelope and body structure
Searches messages that match specified criteria
Retrieves, selects and manages mailboxes (supports SPECIAL-USE, XLIST, CHILDREN extensions which enable special folder flags like Sent, Drafts, Spam, Trash)
Copies, uploads, sets flags, deletes messages on the IMAP4 server
Moves messages between mailboxes (the IMAP4 server must support MOVE extension)
Provides event notification mechanism and background processing
Supports logging IMAP4 session into the file
Executes user-supplied commands
Ping method for keeping connection alive
Idle method (the server must support IDLE extension)
GetMailboxQuota method (the server must support QUOTA extension)
Automatically decodes received messages from MIME format
Automatically generates plain-text version for HTML-only messages
Supports UIDs
Supports secure authentication methods (including OAuth 2.0, CRAM-MD5, NTLM, GSSAPI/NTLM, GSSAPI/Kerberos, Integrated Windows Authentication)
Full and automatic support for Unicode and UTF-8. Supports international headers, attachment names, bodies, etc
UTF-7M mailbox names
GetCapabilities method to obtain the list of extensions supported by the server

SMTP Object

Supports Office 365, Gmail, and other providers.
Can send any Message object to SMTP server
Can send messages to IIS SMTP queue or to MailBee Message Queue or MailBee.NET Queue system instead of direct sending to SMTP server. Using MailBee Message Queue (or its modern replacement MailBee.NET Queue) allows SMTP component to operate very quickly because messages are actually delivered in a background ("fire and forget" delivery)
Supports ESMTP authentication, including secure authentication methods (OAuth 2.0, CRAM-MD5, NTLM, GSSAPI/NTLM, GSSAPI/Kerberos, Integrated Windows Authentication)
Can relay (blind-forward) messages stored in disk files (RelayMessage method)
Supports creating plain-text and HTML messages. For HTML messages HTML Import option is available (it allows to export HTML files with embedded graphics, style-sheets, etc. in one ImportBodyText method call)
Provides method to add custom MIME-headers (AddHeader method)
Supports unlimited number of attachments
Full and automatic support for Unicode and UTF-8. Supports international headers, attachment names, bodies, etc.
Can preserve original formatting of plain-text keeping long lines unwrapped but still providing compatibility with MIME rules (BodyEncoding property)
Includes method MakeAltBody to create plain-text version of HTML body if plain-text version is not available
Supports logging SMTP session into the file
Supports event mechanism to track retrieval progress (and abort sending if needed)
Executes user-supplied commands
Can determine MX server for the specified e-mail address domain (allows for "direct send" without SMTP relay server)

SSL Object

Secure SSL/TLS communications for SMTP, POP3 and IMAP4 protocols
Both dedicated port and "STARTTLS over regular port" communications
SSL support is up to TLS 1.0/1.1/1.2
Client and server certificates. Trusted certificate check, search and select client certificate, option to automatically add server certificate to the store, custom certificate stores including registry and file stores
PFX support

SMIME Object

Can encrypt and decrypt e-mail messages using the different encrypting algorithms
Can sign e-mail messages with digital signatures and verify the integrity of these messages
Because SMIME object secures messages using Message object, all securing functionality of SMIME object also applies to the Message object
Provides properties and methods for managing the digital certificates that are used to secure the e-mails: trusted certificate check, search and select client certificate, add certificates to the specified store, custom certificate stores including registry and file stores
PFX support

Message Object

Available in all MailBee Objects packages (POP3, IMAP4, SMTP, Objects). Used as a main unit POP3/IMAP4 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 display HTML messages saving all necessary files
Can create HTML messages importing all necessary files
International character sets, Unicode, UTF-8, IDN domains fully supported
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
E-mail address validation (both e-mail address syntax and domain MX lookup)

Attachment Object

Also available in all MailBee Objects packages as a part of Message object
Content of attachment is available directly through Content property. You do not have to save a file to disk first and then read it to get attachment content
SaveFile method allows you to easily save attachment content to disk
Supports international and encoded filenames
IsInline property allows to determine whether attachment is an object related in HTML message body (such as embedded image or CSS file) or not (i.e. attachment was explicitly added by the user)
ContentID and ContentType properties are also available
