No! A mailbox could never go over quota if such mails would be rejected! 
If you send one email being 800% over quota cyrus will deliver the mail 
and all next mails to the same mailbox now being over quota will be 
handled appropriate to your imapd.conf settings!

 From imapd.conf manpage:

lmtp_over_quota_perm_failure: 0
          If enabled, lmtpd returns a permanent failure code when
          a  user's  mailbox  is  over  quota.   By  default, the
          failure is temporary, causing the MTA to queue the mes-
          sage and retry later.

quotawarn: 90
          The percent of quota utilization over which the  server
          generates warnings.

Some email clients show a dialogbox (like Outlook) where others do not 
(like Mozilla-Mail). That you did not get a warning right now can be 
caused of your MTA queueing the message caused by 
lmtp_over_quota_perm_failure not being set!
