If so, isn't it odd that the message body, which is also ISO-2022-JP per
the Content-Type header, is readable?

The Subject lines in the compressed mbox format do indeed read
correctly. However I noticed that the subject line in the
archived messages fetched from the list server and the messages received
from the list here are different. Only the list server's archived
messages define the charset. It is not present in the messages received
from the list. The text of the subject appears to have changed as well.

Interestingly, when "View Source" is used for any of these messages in
claws-mail, the subject and body are completely unreadable.

Thank you for trying to figure this out.
