  • Improved support of signed/encrypted e-mails n Outlook Converter.
  • Much faster and more accurate handling of inline images in e-mails with embedded resources. MailMessage.GetHtmlAndSaveRelatedFiles and other similar methods affected.
  • Documentation improvements, mostly in S/MIME (e.g. explains how to set the most secure hashing and encryption algorithms).

• 12.0

  • .NET Core 2.0 / .NET Standard 2.0 edition revised and improved, including better support of .NET Core 2.1 and 2.2.
  • .NET Standard 2.0 support in UWP. UWP apps targeting Windows 10 Fall Creators Update and newer can use the fully-functional .NET Standard 2.0 edition of MailBee.NET Objects. Special UWP edition of MailBee.NET Objects which can work with older UWP platform is still there as well.
  • .NET Core 2.0 sample projects and tutorials added (UWP, console and ASP.NET Core). They feature OAuth 2.0 authentication against Google (Gmail.com) and Microsoft (Live.com, Outlook.com, Hotmail.com) providers along with sending and receiving e-mail using these providers.
  • Improved support of Outlook Converter functionality on iOS and Android.
  • EWS is now supported for .NET Core (.NET Core 2.0+ required). However, only async methods are supported (in .NET Framework edition it's quite opposite, only sync method are supported - this is the limitation of the Managed EWS API).
  • EWS and PDF functionality was moved into friend assemblies. Because EWS and PDF are dependent on other libraries, this caused these libraries be included in the project even if they are not actually needed. Now if the app does not use PDF or EWS, the corresponding libraries will never be referenced, neither directly nor indirectly. Separate Nuget packages for MailBee.NET.EWS and MailBee.NET.PDF were added as well.
  • Exception messages now suggest setting SslProtocol to TlsAuto in case if SSL/TLS handshake fails due to unsupported protocol (usually TLS 1.0 in case if the server requires TLS 1.2).
  • More accurate handling of SSL/TLS related exceptions (now throws MailBeeException instead of system-level AuthenticationException).
  • TLS 1.2 is now fully supported in .NET 2.0/3.5 (despite the fact that .NET 2.0/3.5 itself does not support anything better than TLS 1.0).
  • Documentation now highlights that you must install System.Text.Encoding.CodePages NuGet package for .NET Core 2.0+ apps.
  • Added ConfigureAwait(false) in all internal async calls.
  • Memory/performance optimizations on reading .EML data from stream.
  • MailMessage.GetHtmlAndSaveRelatedFiles and other similar methods now support cid:filename-like CIDs.
  • MsgConvert.PreferAddressesFromInternetHeaders property lets you control from which parts of .MSG file to extract the headers (as sometimes the .MSG file can have these values available in multiple locations and these values are not the same).
  • MessageBuilderConfig.SetDomainKeysSignOnSend property enables automatic DKIM signing when sending the message.
  • Empty headers are now added to the message being sent in case if they are DKIM signed.
  • S/MIME signatures are now time-stamped by default. Smime.TimestampOnSign property lets you turn this off (as it's a time-consuming network operation).
  • S/MIME signatures now include full certificate chain, can be turned off with Smime.IncludeWholeChainOnSign property.
  • Envelope.HasSystemFlag, a helper method to check the envelope for particular IMAP flags.
  • OAuth 2.0 is now supported in EWS, see Ews.SetCredentials(ExchangeCredentials) method.
  • Bounce database updated.
  • Misc. bugfixes to the code and documentation.
  • Also tested with Visual Studio 2019.
  • License keys in a new MN120 format. If you have a valid maintenance contract, contact us to receive your new key. If your contract has already expired, you need to renew it first.

• 11.2

  • .NET Core 2.0 / .NET Standard 2.0 edition (including BounceMail and mail merge over database support).
  • Support of UWP Release builds.
  • Protected constructors added for all exception classes (required for serialization).
  • Empty MAIL FROM is now allowed for SMTP.
  • No extra CRLF in the end of DATA transmission in SMTP.
  • MAIL FROM now includes SIZE if the SMTP server limits the size of messages being submitted.
  • Short path for SMTP authentication (AUTH method_name initial challenge). Fixes issues with Microsoft's SMTP.
  • Misc. bugfixes and documentation fixes.

• 11.1

  • New RblFilter class to perform spam filtering using DNS RBLs.
  • Better support of certificates in .NET Core and Xamarin. Can now use client certificates in SSL/TLS connections and DKIM.
  • Imap.SetSeenForEntireMessages is now false by default. This means MailBee won't set SEEN flag when downloading entire messages unless you change this property value.
  • New Global.DnsServers property to override the default list of DNS servers assigned for the current system. Useful if DNS server autodetection is not supported on the current platform (e.g. Xamarin).
  • New TimeStamp.IP property which represents the IP address the message came from.
  • Improved autodetection of inline images in Outlook .MSG files.
  • Misc. bugfixes.

• 11.0

  • .NET Core edition, .NET Core 1.0/1.1, .NET Standard 1.3 and Xamarin compatible.
  • UWP edition (Universal Windows, UAP 10.0).

  • sha256 signatures in addition to sha1 for all MailBee.NET dlls.
  • IDN domains (e-mail addresses with international domains) support for both sending and parsing.
  • MailMessage.GetHtmlWithBase64EncodedRelatedFiles method to save HTML body with related images being directly embedded in the HTML so that there is no need to save them locally and delete them afterwards.
  • STARTTLS secure connection is now supported in direct send mode. To activate, use mailer.DirectSendDefaults.EnableStartTls = true where mailer is Smtp instance.
  • SecurityProtocol now includes TlsAuto value which you can use to restrict MailBee to use the best supported TLS protocol (up to TLS 1.2). E.g. imapClient.SslProtocol = SecurityProtocol.TlsAuto where imapClient is Imap instance.
  • Imap.GetSpecialFolder method to easily locate folders like Sent Items or Drafts.
  • GetStream method of Imap, Smtp, Pop3 classes now lets you get access to the underlying network Stream.
  • SocketCreating event of Imap, Smtp, Pop3 classes lets you use your own socket initialization. This is especially useful for UWP apps to configure which SSL certificate errors can be tolerated. For instance: Imap.SocketCreating.
  • Outlook 2016 .MSG format support.
  • Support of distribution lists in .PST files.
  • MailMessage.Sender property added.
  • New Logger.DateTimeFormatTimeOnly and Logger.DateTimeFormatFull properties to configure datetime formats in the log file.
  • SmimeResult.SignedCmsResult and SmimeResult.EnvelopedCmsResult properties to give access to SignedCms and EnvelopedCms data of S/MIME messages.
  • Smtp.TransientErrorOccurred event to decide what to do on transient SMTP errors in case if another SMTP server available. The app can either stop trying or try with another SMTP server. The default behavior is to retry in case of relay servers and stop trying in case of MX servers.

  • Revised samples.
  • New documentation look.
  • Tested with Windows 10, Visual Studio 2015, .NET Framework 4.6.
  • License keys in a new MN100 format. If you have a valid maintenance contract, contact us to receive your new key. If your contract has already expired, you need to renew it first.

• 9.0

  • OAuth 2.0 can now work via Google API Auth Client library which supports all OAuth 2 capabilities provided by Google including Service Accounts. DotNetOpenAuth support is still available. New OAuth2.GetXOAuthKeyStatic method for that.
  • New OAuth 2.0 tutorials for Windows and ASP.NET MVC apps.
  • FIPS 140-2 compatibility enforcement with MailBee.Global.FipsMode property.

  • Smtp.SubmitToPickupFolder now preserves international characters in x-sender and x-receiver if they are present in e-mail addresses.
  • Imap.SetSeenForEntireMessages property to easily control whether downloading entire messages should set SEEN flag or not (enabled by default).
  • IMAP MOVE extension support (if the server supports MOVE, moving messages no longer involves copying + deleting).
  • IMAP CHILDREN support (FolderFlags.HasChildren and FolderFlags.HasNoChildren flags make it easier to work with large number of nested folders).
  • IMAP SPECIAL-USE extension support (such as new folder flags like FolderFlags.Archive).
  • New TnefParser class to parse standalone winmail.dat files.
  • MailMessage.ImportRelatedFiles now works much faster with HTML-embedded images (like <img src="data:base64block">).
  • AttachmentCollection.Add now adds attachments from URLs when NewAttachmentOptions.PathIsUri flag is set.
  • .EML attachments (having "rfc822/message" content-type) are now added "as-is" by default, no extra base64 encoding applied. This eliminates issues with reading forwarded e-mails in some e-mail clients which cannot decode .EML attachments from base64.
  • E-mail parser can now process e-mails having CR line endings (in addition to standard CRLF and sometimes used LF endings which have already been supported before).
  • Global.FixBadDates property to allow invalid Date values in e-mail messages (often the case when parsing spam e-mails).
  • Auto-detection of an attempt to load Outlook .MSG file as if was .EML MIME file. Earlier the message was initialized with garbage, now MailBee will throw an exception.

  • SASL PLAIN login authentication method now tolerates the response which cannot be decoded from base64.
  • The password of an account on a mail server can now be empty (for instance, some SMTP servers require authentication with non-empty username but empty password).
  • AuthenticationOptions.BypassLoginProcedure flag which lets you call Login method of Imap, Pop3, Smtp class without sending anything to the server. Useful if you're doing your own custom login method which is not SASL compatible (for custom SASL logins, SaslLogin class must be inherited).
  • When Logger.DisableOnException is enabled, UnauthorizedAccessException during logging operations will now also be suppressed (earlier, only IOException was suppressed).
  • Log files now include SSL handshakes.
  • MailBeeException.Message property, when the exception has InnerException, now checks if that InnerException also has InnerException, and includes its text as well. This helps understand the cause of the issue in case of deeply nested exceptions.
  • RSA certificate parsing fix (handles the situation when RSA parameters are 63 bytes in length instead of 64 bytes).
  • Smtp.MessageNotSent event no longer causes ParameterCountMismatch exception.
  • SMTP XTEXT protocol fix (used in requesting a delivery status notification, DSN).

  • MailBee.Html processor fix.
  • Lots of Outlook Converter fixes of .MSG and .PST conversions.
  • TNEF parsing fixes.
  • License keys in a new MN900 format. If you have a valid maintenance contract, contact us to receive your new key. If your contract has already expired, you need to renew it first.

• 8.0

  • All-new EmailAddressValidator component (in MailBee.AddressCheck namespace). Checks bulks of e-mail addresses for syntax and existence. Available both as part of MailBee.NET Objects bundle and under separate license.
  • Added support of mail merge over System.Data.IDataReader, with a number of samples using MS SQL Server database for mail merge.
  • The default charset for new e-mail messages is now "utf-8" (makes creating international e-mails a bit easier)
  • New Smtp.ValidateEmailAddressSyntax method.
  • Support of OAuth v2.0 with OAuth2 class, for all mail protocols. Confirmed to work with Gmail and its XOAUTH2 extension.
  • Constructor overloads accepting license key added, for all licensed components.
  • Imap.DownloadEnvelopes now accepts bodyPreviewSize=-2 to download entire messages but keep them UNSEEN.
  • Easier to understand exceptions when the license key is invalid but it's still a MailBee key (of an older or ActiveX/COM version).
  • MailBee now sees the license key stored in 64-bit registry even when running in a 32-bit process (only for .NET 4.0+ optimized version). For .NET 2.0/3.5, the documentation updated on how to deal with this situation.
  • Some enhancements to the logging subsystem. Large chunks of data are logged with their beginnings and endings for easier preview, LogNewEntry.ToString method added.
  • Improved IPv6 compatibility.
  • Timeout setting now affects not only socket Read and Write operations but Connect as well, for all mail protocols.
  • Added timeout for how long a single SMTP response can be returned by the server added (utilized automatically), to avoid slow-downs with mail servers which return EHLO response very slowly, such as by a single byte every 10 seconds, resulting in several minutes of total time per response.
  • New MailBeeConnectionException.WasConnected property for more accurate error handling.
  • Improved support of Outlook .MSG and .PST conversions.
  • Improved MIME parser and builder, including the support of international characters (especially in headers and attachment filenames), quoted strings in headers, and more.

  • Errors during Disconnect are handled more gracefully.
  • Reading files from a network share now made in a more reliable way.
  • Revised documentation (added the detailed guide for using EmailAddressValidator, many topics across Assembly Reference have been extended or clarified, more code snippets added).
  • Revised samples. Amongst improvements, the samples now access C:\Temp instead of C:\ to honor UAC restrictions.
  • Extended and improved MailBee.NET Start Menu launcher.
  • Extended and improved SaveKeyGui and SaveKey tools. Now they can save the license key to both 32-bit and 64-bit registry on 64-bit systems (important for .NET 2.0/3.5 apps which can't see 64-bit registry from 32-bit processes). Also, SaveKey tool can now clear the key from the storage, not just put it there.
  • New large sample project named AddressValidatorDemo. Useful not only for verifying e-mail addresses in bulk, but also for implementing mail merge over database and other multi-threaded, database-oriented and asynchronous operations with MailBee.NET Objects as it highlights many useful techniques not necessarily related to checking e-mail addresses.
  • License keys in a new "MN800-" format. If you have a valid maintenance contract, contact us to receive your new key, or renew the maintenance if your contract has already expired.

• 7.3

  • COMPATIBILITY: New improved mechanism of auto-detecting DNS servers and new flags for DnsServerCollection.Autodetect(DnsAutodetectOptions) method. Some flags have been removed from DnsAutodetectOptions enumeration.
  • COMPATIBILITY: Message-ID (such as MailMessage.MessageID) now returns its value enclosed in angle brackets "<>".
  • COMPATIBILITY: The standard argument of EHLO/HELO commands is now the IPv4 address of the local system, not the domain of "From" address. Seems to work better with some servers which check this argument value. Still, it's better to specify it manually with Smtp.DirectSendDefaults.HelloDomain property to the public domain name of the system.
  • New ImportBodyOptions.PreferCharsetFromMetaTag flag. Use it when importing HMTL with international characters.
  • New SmtpMessageRecipientSubmittedEventArgs.AllowRefusedRecipient property allows for manual control of allowance of failed recipients during sending e-mail to multiple recipients.

  • 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 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 asfalse 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.

• 6.0

  • New FIPS-compatible licensing algorithm makes no use of MD5. This allows using MailBee.NET Objects in FIPS-restricted environments such as many banking and government structures.

  • Pop3.InboxPreloadOptions can now take advantage of Pop3InboxPreloadOptions.List to further optimize memory usage.
  • Outlook Message Converter refactored. Now it's in the new namespace Outlook, easier to use and more flexible, provides more methods and properties, fine-tuned in many places. Old OutlookMsgnamespace is still supported for backward compatibility but it's now deprecated and removed from the documentation.
  • New AddJob overloads in Smtp class to allow submitting send mail jobs from .EML files and user-supplied MailMessage objects. Allows for more flexibility and memory savings.

  • 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).
