Thanks again for looking into it! The sending software seems to be
open-source [1]; I've asked on GitHub for a sample that can be shared
[2]. 🤞

My original hope was that once you figure out the reason you could
create a synthetic example. Unfortunately I don't have control over the
sender side myself, I can only ask them to send me an email over this
system. And because it's a (hosted) production instance it will always
include personal data (of the sender) that shouldn't be published. :-/

It's fine to share with individual developers of other projects like
libgmime, though, as long as it doesn't end up anywhere public (e.g. git
repo, public bug tracker).
