• Documentation now mentions how to use Global class and its properties (like Global.SafeMode) in Visual Basic where Global is a keyword

What's new in MailBee.NET 6.8
The latest MailBee.NET Objects release allows you to greatly speed up downloading e-mails in your IMAP applications, makes it easier to use DKIM and DomainKeys, can extract RTF body from winmail.dat attachments, and more.

With Imap.DownloadEnvelopesEx method, you can join multiple IMAP commands for downloading message data in a single batch. The pipelined execution of commands may result in 1000% performance boost, and there is no typo here! It's especially efficient when you download text body of multiple e-mails without downloading entire messages.

Also, IMAP and POP3 components now support negative message indexes. For instance, you can easily access the last e-mail in the folder with -1 index.

Many improvements were made to Outlook .MSG, .PST and TNEF parsers. As an example, you can now extract RTF message body from MS-TNEF (winmail.dat attachment).

DKIM signing and verification made easier with MailMessage.DomainKeysSign and MailMessage.DomainKeysVerify methods. You also no longer need Smtp license to verify DKIM signatures and can sign with DKIM during mail merge.

Other improvements include:

• MailMessage.Parser.FixCrLf property to deal with e-mails not having the correct CrLf sequence at the end of each body line
• XOAUTH and IMAP XLIST fixes (important for Gmail users)
• Better and user-controlled handling of shared access to spam and non-spam databases in AntiSpam component
• Added new bounced e-mail formats

What's new in MailBee.NET Objects 6.7:

• Support of OAuth authorization and XOAUTH authentication enables applications to access e-mail resources without requiring end users to give their credentials away to these applications. Widely used by Google, Twitter and many others.
• Much improved HTML-to-RTF transformation during converting .EML files into Outlook .MSG format. HTML-to-RTF engine now supports more tags and creates more accurate formatting in the produced Outlook .MSG documents.
• NTLM and GSSAPI authentication improvements
• A number of fixes to MIME parser and IMAP client
• Revised documentation.

What's New in MailBee.NET Objects 6.6

• Improved legacy .NET 1.1 and .NET Compact Framework support.
• New more effecient .PST file reader supports both 32-bit and 64-bit Outlook .PST files.
• Can access any item in Outlook .PST by its numeric ID.
• Filesystem-compatible names of Outlook .PST folders.
• SmtpServer/SmtpServerCollection DnsServer/DnsServerCollection classes made Serializable.
• Can be used with MailBee.NET Queue companion to send bulk mail to SSL-enabled mail servers.
• Better tolerates not fully RFC-compatible SMTP servers.
• Better multi-threaded access to Bayes spam/non-spam databases.

What's New in MailBee.NET Objects 6.5

• GSSAPI and NTLM authentication rewritten from the ground up, now provides managed implementation for .NET 2.0+ (UnmanagedCode permission is no longer required), supports both Integrated Windows Authentication and explicitly specified credentials for both GSSAPI and NTLM, supports GSSAPI via both Kerberos and NTLM, updated to work with MS Exchange 2007/2010.
• Rewritten unmanaged GSSAPI and NTLM implementation for .NET 1.1 and .NET Compact Framework. Supports everything managed GSSAPI/NTLM .NET 2.0 implementation does.
• New TargetName (Service Principal Name) and UserDomain settings for all mailer components (Login and BeginLogin method parameters for POP3/IMAP, SmtpServer object properties for SMTP). These values can be used with GSSAPI and NTLM.
  COMPATIBILITY: If you use Imap.BeginLogin or Pop3.BeginLogin method in your code written for earlier versions of MailBee.NET Objects, insert "null, null" (C#) or "Nothing, Nothing" (VB.NET) in place of the newly added parameters.
  Simplified authentication procedure (retry with a non-secure method if the secure method fails).
• New flags in AuthenticationOptions to further fine-tune authentication process.
• Improved logging for easier trouble-shooting (now large data chunks in the logs are presented as a short preview and the total size of the chunk).
• Support of IMAP XLIST extension (used by Gmail and many others) enables recognition of special folder flags (Drafts, Sent, Trash, etc).
• Improved support of IMAP APPEND (Imap.UploadMessage method) when used with MS Exchange 2007/2010.
• Improved support of IMAP servers which allow message flags containing special characters (such as Zimbra).
• Memory consumption by Smtp object decreased twice when relaying e-mails from file
• New parameter doubleFirstDotAtLine for methods which submit to IIS SMTP pickup folder works around the issue of IIS SMTP pickup service which results in loosing dot character when it appears at the first position on a line.
  COMPATIBILITY: If you use Smtp.SubmitJobsToPickupFolder or Smtp.SubmitJobsToPickupFolder method in your code written for earlier versions of MailBee.NET Objects, set the new parameter as false if you're submitting to MailBee Message Queue or true if you're using IIS SMTP queue.
  MailMessage.DateSent property allows you to access "Date Sent" value of converted Outlook .MSG files, or make it appear in the resulting .MSG file if you're doing the opposite conversion (into Outlook .MSG).
• Miscellaneous bug fixes and improvements of Mime, AntiSpam and Outlook functionality.
• Miscellaneous documentation improvements (highlights usage with MS Exchange and more).
• The documentation in Visual Studio 2010 format which can be integrated into IDE.

• MailBee exceptions now bear [Serializable] attribute (useful for error tracking when all exceptions which occur in an application are recorded for further analysis).
• BounceMail supports a number of new bounced e-mail formats.
• BounceMail now recognizes MDNs (Message Disposition Notifications). MDNs are similar to DSNs with only difference they are created by mail clients rather than by mail servers (for instance, receipt of an e-mail containing an MDN may indicate that the recipient has actually opened the e-mail in the mail reader program).
