Re: All mail removed, but it is on the filesystem

The value for expunge_mode has been "delayed" since Cyrus 2.5.0 .



         expunge_mode: delayed

             The mode in which messages (and their corresponding cache 
entries) are expunged. “default” mode is the old behavior in which the 
message files are purged at the time of the EXPUNGE, but index and cache 
records are retained to facilitate QRESYNC. (Note that this behaviour is 
no longer the default, but is so named for historical reasons.) In 
“delayed” mode, which is the default since Cyrus 2.5.0, the message 
files are also retained, allowing unexpunge to rescue them. In 
“immediate” mode, both the message files and the index records are 
removed as soon as possible. In all cases, nothing will be finally 
purged until all other processes have closed the mailbox to ensure they 
never see data disappear under them. In “default” or “delayed” mode, a 
later run of “cyr_expire” will clean out the retained records (and 
possibly message files). This reduces the amount of I/O that takes place 
at the time of EXPUNGE and should result in greater responsiveness for 
the client, especially when expunging a large number of messages. 
Allowed values: default, immediate, delayed
