It shouldn't even try this.. I guess both INBOX directories use the same group? That's why Dovecot's internal check fails to realize that it can't use link(). This is now fixed in v2.1 hg tree. Too big of a change to fix in v2.0. You could work around it by using unique GIDs for users, or patching Dovecot's source code (mail_storage_copy_can_use_hardlink() to always return FALSE)
