We are trying to move our mail store from a host running cyrus-imapd 2.2.12 under CentOS-4 to one running 2.3.16 under CentOS-6. The current host is a 32 bit architecture. The new host is 64 bit. We have followed the update guide found at: http://www.cyrusimap.org/docs/cyrus-imapd/2.3.16/install-upgrade.php The steps we followed were: 1. Install cyrus-imapd et al on the new host. 2. Modify /etc/cyrus.conf and /etc/imapd.conf to suit our requirements. 3. On the old host dump the mailbox.db in flat format using /var/lib/cyrus-imapd/ctl_mboxlist -d > mboxlist.txt 4. Copy the mboxlist.txt file and the mail spool from the old to the new system 5. Run SELinux restorecon -fr on /var/spool/imap to set the correct contexts and ownership. 6. Load mailbox.db from mboxlist.txt using cat mboxlist.txt | /usr/lib/cyrus-imapd/ctl_mboxlist -u 7. Run /usr/lib/imapd-cyrus/reconstruct -rfg user 8. Run /usr/lib/imapd-cyrus/reconstruct -G user 9. Run /usr/lib/imapd-cyrus/quota -f 10. Start saslauthd and cyrus-imapd services. All the transferred mailboxes are seen and the imapd configuration data seems correct. The problem is that the quotas reported for each mailbox tree do not seem to aggregate under 2.3 as they did on 2.2. So, for example a user with an overall allocation of 500Mb reporting 70% utilization for the INBOX on the 2.2.13 version reports 3% on the 2.3.16 server even though the contents of the mailbox trees are identical. It seems that the new version calculates quota only for the INBOX itself, and not for all of the sub-directory contents. Is this a change in behaviour for 2.3 vice 2.2 or do I have a problem? Has anyone run into this and if so, how was it resolved? -- *** E-Mail is NOT a SECURE channel *** James B.
