MailBee.NET Objects v6.0: low memory usage, FIPS and Outlook .PST support

Thursday, 08 July 2010
We have just released a new major version of MailBee.NET Objects which adds a lot of important features and improvements through the entire library. This includes a memory-efficient mail engine, support of Outlook .PST format, FIPS compliance and other enhancements.

The new version comes with the rewritten mail engine which parses and builds e-mail messages and SMTP/POP3/IMAP requests and responses. The new engine provides better performance and consumes 3-5 times less memory during conversations with mail servers and processing e-mails. We also added some optimization techniques you can use in your applications. These optimizations make it possible to send and receive several hundred megabytes e-mails on 1GB RAM systems.

Outlook component can now process both .MSG and .PST files. New PstReader class allows you to traverse through the folder tree of a .PST file or get the entire tree as a flat list, extract any items like messages, contacts or appointments, access their properties or convert these items into MailMessage objects. PstReader processes items one-by-one so that the entire .PST file or stream never gets loaded in memory completely. This makes it possible to read even very large .PST files containing many thousands of items.

FIPS compliance means you can now use MailBee.NET Objects in the systems which do not allow using FIPS-incompliant security algorithms like MD5. This is especially important for government organizations, banking and military structures.

Other enhancements include better compatibility with MS Exchange 2010, new overloads of Smtp.AddJob method which allow you to implement background relaying e-mails from previously created .EML files, new bounced e-mail formats and Message Disposition Notifications, Serializable exceptions, miscellaneous fixes in the code and the documentation.
