New Features

Added CRAM-MD5 authentication

The ability to authenticate using the CRAM-MD5 mechanism in IMAP, POP3, and SMTP clients has been added. The following code samples show how to use this feature.

IMAP client:

imapClient.AllowedAuthentication = ImapKnownAuthenticationType.CramMD5;

POP3 client:

popClient.AllowedAuthentication = Pop3KnownAuthenticationType.CramMD5;

SMTP client:

smtpClient.AllowedAuthentication = SmtpKnownAuthenticationType.CramMD5;

Cancelation for asynchronous operations

For asynchronous methods of mail clients, overloads have been added with the additional CancellationToken parameter. This allows canceling an asynchronous operation as shown in the code snippet for an ImapClient.

CancellationTokenSource tokenSource = new CancellationTokenSource();
AppendMessagesResult appendMessagesResult = null;
AutoResetEvent autoResetEvent = new AutoResetEvent(false);
ThreadPool.QueueUserWorkItem(delegate(object state)
            appendMessagesResult = imapClient.AppendMessagesAsync(mmList, tokenSource.Token).GetAwaiter().GetResult();
        catch (Exception ex)



Encoding option for MboxrdStorageReader class

We have added the ability to set preferred text encoding when loading Mbox files for reading.

var reader = new MboxrdStorageReader("sample.mbox", new MboxLoadOptions() { PreferredTextEncoding = Encoding.UTF8});
var message = reader.ReadNextMessage();

Using the global formatting options for the Mht header

The global options set the common formatting of an Mht header for all MhtSaveOptions instances. This is to avoid setting formatting for each instance of MhtSaveOptions.

GlobalFormattingOptions.PageHeaderFormat = "SomePageHeaderFormat";
GlobalFormattingOptions.HeaderFormat = "SomeHeaderFormat";
GlobalFormattingOptions.BeforeHeadersFormat = "SomeBeforeHeadersFormat";
GlobalFormattingOptions.AfterHeadersFormat = "SomeAfterHeadersFormat";

// saveOptions1 and saveOptions2 have the same mht header formatting
MhtSaveOptions saveOptions1 = new MhtSaveOptions();
MhtSaveOptions saveOptions2 = new MhtSaveOptions();
