I found the -a option on cyr_expire to ignore the annotations, but that 
didn't help. Today  I ran cyr_expire -X 1 -v -a and it's still saying

$ /usr/lib/cyrus-imapd/cyr_expire -X 4 -v -a
Expunging deleted messages in mailboxes older than 4.00 days

Expired 0 and expunged 0 out of 0 messages from 0 mailboxes

Looking at unexpunge -l user/name at example.com I can see hundreds of 
messages, the Expg date going back to at least the start of March, but 
it still won't delete any.

I've had no answers anywhere on the internet (and I've not been 
backwards about asking). Do I change the expunge_mode to delete them 
immediately? Will that get rid of the old files at that point or will I 
have to do that manually?



Thanks
Tom.
