No, I wasn't sure if reconstructing would bring back expunged e-mails or 
not. Plus I had 3893 accounts showing these errors and once cyr_expire 
started working with -X1 I didn't pursue reconstruct. :-)

One thing I forgot to mention is that /var/imap is on an ext4 filesystem 
and all the metadata is stored there.


metapartition_files: header index cache expunge squat
metapartition-default: /var/imap/metadata
delete_mode:delayed
expunge_mode:delayed
