[Dovecot] Quota, message is never send?

[Luuk@dovecot]

I think i have quota setup correctly, but finally time arrived to check
that ;)

opensuse:/etc/dovecot # doveadm quota get -u luuk
Quota name Type Value Limit %
User quota STORAGE 571973 716800 79
User quota MESSAGE  45555      -  0

It seems i am at 79% of my quota
so, i added a line to conf.d/90-quota.conf, to get a wraning when quota
exceeds 10%:
....
plugin {
  quota_warning = storage=95%% /usr/local/bin/quota-warning.sh 95 %u
  quota_warning2 = storage=90%% /usr/local/bin/quota-warning.sh 90 %u
  quota_warning3 = storage=10%% /usr/local/bin/quota-warning.sh 10 %u
}
....

But this message is never send, what am i missing (in my config)?
