problem deleting messages with cyrus-imapd 2.3.3-6

[Rich Graves]

This is the "delayed expunge" feature, added in 2.3. man imapd.conf, 
page down to expunge_mode. It's a speed enhancement and has the side 
effect of allowing sysadmin undelete/unexpunge without recourse to backups.

You should have something like this in cyrus.conf for garbage 
collection. man cyr_expire for details.

delprune      cmd="cyr_expire -E 2 -X 2" at=0400
