I'm wondering about some filesystem considerations when using Dovecot. I've read https://wiki.dovecot.org/FileSystems, but that basically talks about low-level details. My question is not about that.
I use the following mail_location: maildir:~/maildir:LAYOUT=fs:INBOX=~/maildir/INBOX:UTF-8
In this setup, because I use LAYOUT=fs and UTF-8, the IMAP names are identical to the directory names. I noticed that the INBOX name is case-insensitive, but all other names are case-sensitive. I wonder if it's possible to have consistent behaviour here.
Now since I use ZFS, I have the ability to make the filesystem case insensitive and to normalise unicode codepoints. Is that something that would be useful when running a Dovecot server, or would that be a bad idea?
