ImapProtocollException when fetching BodyStructure

[jsaf80]

I'm fetching the BodyStructure of Mails in gmx.net and get an ImapProtocollException with immediately disconnecting the Client.

Here is the Protocoll from 3 Mails which triggers the Exception:

*Added **** to hide my emailaddress

How can I workaround the faulted bodystructure?

The above commit should work around the IMAP server bug for you. You can test it out by grabbing the latest nuget from https://www.myget.org/feed/mimekit/package/nuget/MailKit

The version will be 2.2.0.11 (I think) when CI finishes building and pushing the resulting package.

Check the myget URL in about an hour or so and it should have the build.
