Right. I looks like there are indeed many message-ids in the resulting
database that look like valid email addresses. So that problem persists,
despite an attempted fix discussed in that thread.

I was wondering if the exception could result from overflowing some
internal limit due to threads many thousands of messages long. I will be
hard to know until I can replicate the exception. Perhaps a more
complete org-mode list archive would do it.
