Wumple.com

Welcome to part four in the series about our upgrade of wumple.com to Fedora Core 6 from Fedora Core 2.  The closing of the Fedora Legacy project and thus no future security updates for FC2 spurred this upgrade.

Part 4 features cyrus-imapd, the IMAP email server which I use because it supports IMAP IDLE push email which I use with ChatterEmail on my Palm Treo 680.

Cyrus-imapd:

Fedora Core 6 added some scripting to export and import some Cyrus-imapd database files in case new versions of BDB (Berkely DB, the DB library Cyrus-imapd uses) change the DB format.  Unfortunately something appears to break this script. 

See this email from info-cyrus for some discussion about the matter.

The following directions by langthang via Grzegorz Mucha (which I have modified for FC6 paths) worked around the problem (though I hope cyrus-imapd properly rebuilt the files these directions delete):

$ sudo /etc/rc.d/init.d/cyrus stop

$ sudo -u cyrus bash

$ cd /var/lib/imap/

$ mkdir backup

$ cp -a * backup

$ rm db/*

$ rm db.backup?/*

$ rm deliver.db

$ rm tls_sessions.db

$ /usr/lib/cyrus-imapd/ctl_mboxlist -d > mailboxes.txt

$ mv mailboxes.db mailboxes.db.old

$ /usr/lib/cyrus-imapd/ctl_mboxlist -u < mailboxes.txt

$ diff mailboxes.db*

Files mailboxes.db and mailboxes.db.old differ

$ sudo /etc/rc.d/init.d/cyrus start

I used to have to recompile the cyrus-imapd src rpm to enable IMAP IDLE support, but it appears that this option is now enabled by default in the pre-built rpm package.
