Yes, the updated version of their Common Library (v4.0.6) fixes both MailKit and MimeKit issues. However, I don’t see that version on the public download list yet. You could try contacting them directly for it, I suppose.

Mandeeps support has prepared an updated version of their Common Library (v4.0.6) which fixes the issue and should be published soon.
