By "not set" you mean it doesn't exist at all, or it exists but is empty?

If dcMailQuota isn't returned, then the global quota_rule is used. If it is returned as empty, I guess it gets treated as unlimited quota. There's currently no easy way avoid this (a difficult way could be e.g. post-login scripting, but that works only for imap/pop3).
