dovecot - Sep 2012 - Changing Quota downward for special Mailboxes? (2.1.6)

It seems there is no way to correct te quota limit downward for some
mailboxes, like:

quota_rule9 = UCE-TMP:storage=-10%%

The idea is to not eat up the users storage with spam, so that spam
stays in the queue (for some time) while real mail gets delivered.

There *is* a line

                } else if (*value != '-' && relative_rule) {

in quota.c, but nothing else handles it, starting with
quota_rule_parse_percentage.

Interesting idea. This was pretty easy to fix:

Now, the next problem is that if LDA can't save the message to UCE-TMP
because of quota failure it saves it to INBOX. I'm not really sure how that
should be fixed, since generally it's a good idea to do it..
