For cyr_expire (in cyrus.conf) - I have:

 delprune      cmd="cyr_expire -E 3" at=0400

I have no setting for 'expunge_mode' in imapd.conf - having checked, 
"Immediate" mode is the default behavior in which the message files and 
cache entries are purged at the time of the EXPUNGE"

I didn't realise cyr_expire did anything other than expire the duplicate 
supression stuff - and I didn't know 'expunge_mode' existed.

Having said that - would the 'cyr_expire' line above (and the apparent 
'default to immediate') explain why the files are remaining behind?

Thanks,
