Subject Contains New Line and Carriage Return

[Francis73]

Using the latest version of Aspose.Email 21.8.1 (.Net) we have encountered, for long subjects a carriage return linefeed is being placed in the string.

Actual Subject:

Processed Subject:
[eBook] Discover the Benefits of Making Payment Optimization a Part \r\nof Your Core Payment Strategy

Attachment names containers newline and carriage return after upgrade

We recently upgraded Aspose.Email from version 19.3 to 20.6 and am running into some problems after the upgrade. For certain emails the attachment names now contain newline and carriage return characters that doesn’t seem like they should be part of the attachment name. Example code: LoadOptions loadOptions = new EmlLoadOptions(); MapiMessage msg = MapiMessage.load(filename, loadOptions); System.out.println(StringEscapeUtils.escapeJava(msg.getSubject())); msg.getAttachments().forEach( atta…

@Francis73,
Thank you for posting the query. Could you share the message file and code example reproducing the problem, please?

I have investigated this further and it appears the issue is the ImapClient.FetchMessage (https://reference.aspose.com/email/net/aspose.email.clients.imap.imapclient/fetchmessage/methods/5) method.
Loading the message with the MailMessage.Load function returns the subject without the new line and carriage return characters.

I have included the code below and I have attached the sample message.
You will need to enter your details in the GetClient method and update the SelectFolder with a valid folder.

Please let me know if you require anything else to investigate.

    {
        var g = new Aspose.Email.License();
        g.SetLicense("Aspose.Email.NET.lic");
        // Has carriage return and new line
        LoadViaImap();
        // Correct
        LoadMessage();
    }

    static void LoadViaImap()

            client.SelectFolder("AsposeTesting_Inbox");

            foreach (var messageInfo in messages)

@Francis73,
Thank you for the additional information. I reproduced the problem with breaking the message subject into two lines and logged the issue with ID EMAILNET-40399 in our tracking system. Our development team will investigate this case. You will be notified when the problem is fixed.
