I’m am still getting the errors I mentioned previously. Maybe half a dozen of them per day . . .

So, the location of my mail storage (/mnt/volume1/mailserver/plain/maildir/%d/%n/) is a filesystem mounted by gocryptfs. Do you think gocryptfs could be at fault here?

Before and after mounting: What are the mount folder's user/group permissions? Who owns the mount folder (user/group)?

If you do a "stat /mnt/volume1/mailserver/plain/maildir/domain.com/user/dovecot.index.log" as the user dovecot is running as (from your mail I see austin owns that file - is dovecot run as user austin?) - do you also get an error?

If you do get an error - could you create a small encrypted fs and mount it to another folder, create a file there and check again for "stat file"? Play with the permissions and user/group assignments. Still getting an error?
