I have realized that I may be wrong. I confused november.he-3.net and
november.he.net-3. Perhaps november.he-1.net was obtained from your
email using an autoconfiguration protocol. However I am still surprised
that 2 ImapMail directories have been updated.
If you are interested in going deeper, I would check modification time
of various files under november.he*.net and would had a look into
.thunderbird/dpchrist/prefs.js. Currently used dirs are like
mail.server.server1.directory (with various numbers).
There are some open bugs related to changing server name, e.g.
https://bugzilla.mozilla.org/show_bug.cgi?id=1483485
however I am unsure that any of them may be relevant to your configuration.
