MimeMessage.TextBody not returning body

seasonedtofu commented 4 months ago

Describe the bug MimeMessage.TextBody is not returning the text body, I can see that it exists within the body itself if I call MimeMessage.Body The response I get is null

Platform (please complete the following information):

OS: Windows (running .Net app in a dockerized container)
.NET Framework: .NET 6
MailKit Version: 4.3.0

To Reproduce Steps to reproduce the behavior: Call .TextBody on a MimeMessage

Expected behavior To return the text body instead of null

Code Snippets

var message = inbox.GetMessage(uid);
var test = message.TextBody;
Console.WriteLine(test);

The TextBody and HtmlBody properties follow a heuristic approach that is based on common MIME structures used by the most widely used mail client apps.

The problem with MIME is that there is no guaranteed way to always locate the 1 part that is the text body (or the html body) of a message. It's also very subjective.

I'll take a look at it, but I'll need an example message that illustrates the issue.

That's an html body. Where is the text body? :-)

(hint: there is no text body)
