If you get this message: "Mail cannot save information about your mailboxes because there isn’t enough space in your home folder"...
Check for a home directory access/permissions issue, then try deleting the file "Envelope Index-journal" in ~/Library/Mail or ~/Library/Mail/V6/MailData
Or from the terminal: either for older versions: cd ~/Library/Mail or for newer versions: cd ~/Library/Mail/V6/MailData Then: rm Envelope\ Index-journal
That will force the sqllite database to reindex which will help if a corrupt index has caused this error.
I usually write a blog post about once a week. The latest post can be viewed here: We Need Trump and Musk: I wonder if Trump and Musk might like to visit here after they have finished sorting out America! (posted 2025-02-11 at 11:40:37). I do podcasts too!. You can listen to my latest podcast, here: OJB's Podcast 2025-01-30 Pragmatic Libertarianism: Freedom is important. Maybe it's all that really matters..
