Yes, that was the solution. Add 'separator = "$"' to the 'namespace
inbox {' section of dovecot.conf. Many suggestions were provided,
including one that said it was a long-standing bug with Thunderbird.
This happened after an upgrade, so I knew it wasn't that bug. I was
surprised to find so much outdated dovecot documentation.

Thanks very much to Edgar and the group for helping me resolve this.

Thanks,
Alex
