No, it's filesystem quota so Dovecot can't override it.

The error message is only slightly different: "Not enough disk space" (instead of "Quota exceeded")

With imap_quota plugin it allows IMAP client to see how much quota is used/left. You could also enable quota warnings. And configure the quota exceeded error message.
