It depends on your configuration.. The attachment directory is a setting. I was thinking that it it would typically be the same for all users, so if you have two filesystems, you'd need to decide which one will have the /attachments directory. Or you could put half the attachments to fs1 and the rest to fs2 (/attachments/00 .. 7f to fs1, /attachments/80 .. ff to fs2). Or something like that. If you really want to separate students' and teachers' attachments to separate filesystems, you'll then have userdb return a separate attachment directory for either students or teachers. Then they won't share anything and Dovecot doesn't even know the existence of the other attachment storage.
