I have a cyrus-2.2.3 installation with quotas appearing as flat files in /var/lib/imap/quota/(a-z)/user.* Each file has 2 lines, the quota and the current useage. I process these files to generate quota warnings for users in advance of reaching their limit. In the imapd.conf(5) man page for this distribution, there is no configuration choice for quota_db . In my new 2.3.7 RHAS5 distribution, quota_db choices are quotalegacy(default), flat,berkeley,berkeley-hash,skiplist. What is quotalegacy - is it what I have in my 2.2.3 distribution? How is this different from flat? confused, S ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
