Not really. They can of course create hardlinks elsewhere in /home.

It's not chrooting anywhere yet with those settings. Hmm. I think I'd
need to add "mail_chroot" setting which would specify the default
chroot.

For now you'd have to change user's home directories to contain /./ to
speficy chroot. Like "/home/./user".
