Lane Cove, Australia, October 22, 2014 --(PR.com)-- What's New in this Release?

Aspose team is pleased to announce the new release of Aspose.Email for Java 4.6.0. Similar to the equivalent .NET version, this month’s release introduces new features that let developers filter spam email messages based on the naive Bayes classifiers. It also brings improvements to the size of generated PSTs. The naive Bayes classifier offers a high accuracy anti-spam message classification and provides an effective measure for distinguishing between spam and ham (non-spam) messages. This month’s release of Aspose.Email for Java introduces this new feature of spam analysis and filtering using the same proven method. Aspose.Email for Java now offers to spam analyzer to filter spam messages. This step is carried out on data sets of spam and ham messages for training the filter. Normally, a set of 100-200 messages each is used for this purpose. Once the sets are ready, the API’s SpamAnalyzer class is used to train the filter with both these sets as inputs. Once the training is complete, the results of the trained classifiers can be stored to disc calling the saveDatabase method of the class. Testing is carried out by presenting sample messages to the test method of the class. Based on the training results, the tests provide the probability of a message being spam or ham. Aspose team has also improved the size of PSTs that are generated using the Aspose.Email API. The PSTs created now are almost 25% smaller in size compared to the previous versions. Aspose team is still working to bring further improvements to this area. Ported from the .NET version, this month’s release includes the same bug fixes, issues with message encodings when converting between different message types, exceptions when loading certain message files and calendar items, Information loss when processing TNEF files, text alignment issues when loading/saving calendar items and many more. The main improved features & bug fixes added in this release are listed below.
