Ok, when I used the gmail account as the mail spool, as your second
message suggested, I got three spam messages that gmail helpfully sent
me. So, the buffer got modified. When I did vm-save-folder, it got
saved.

I did get-new-mail again. There were no new messages. When did
vm-save-folder, it said there were no changes to be saved.

So, it seems ok to me.

Cheers,
