Enhancements

This month’s release introduces a number of enhancements to meet user needs. These are explained in the following sections of the blog.

Creation of DKIM Signed Emails

This month’s release provides the feature of signing email messages with DKIM (Domain Keys Identified Mail) that enables organizations to take responsibility for the message that is in transit. A digital signature is added to the email message headers using the user defined private keys. The API’s MailMessage class provides the method DKIMSign that uses the Crypto Service Provider and DKIM Signature Info for signing the message. Once signed, the message can be sent using the API’s SMTP as well as Exchange Clients.

Pre-Fetch Message Size

Outlook InterOp provides the feature of retrieving message size before actually fetching the complete message from the Exchange server. In case of Aspose.Email API, the summary information retrieved from Exchange server is represented by ExchangeMessageInfo class and represents the only information that is fetched before actually retrieving the whole message. This month’s release enhances the functionality provided by this class to fetch message size as well before the complete message is fetched from the server. This information is represented by the Size property of the class.

Using Encoding in ImapQueryBuilder

We have also enhanced the ImapQueryBuilder for specifying search string encoding while listing messages from IMAP server. This helps querying the strings that are, for example, in Unicode format and were not supported earlier. An example is Turkish characters such as ğüşıöç.

Other Improvements

This month’s release also fixes a number of bugs that were discovered by our valued customers while working with our API. We have fixed them all, resulting in improved API functionality. Some of these include:

  • Issues related to TNEF messages sending via SMTP and Exchange clients
  • Encoding issues while converting messages to other formats
  • Issues related to PST during exporting messages
  • Exceptions while listing messages from IMAP client, loading certain message files, converting messages to TIFF and Exchange Server

As always, we welcome your feedback about the new release. Please feel free to contact us for your queries on Aspose.Email forum.
