expunging deleted messages?

[mikee]

Reading the man page for cyr_expire it seems like this command
is designed to expunge messages that are deleted over -E DAYS
ago. I have a folder in my cyrus-imapd account that I have
a few thousands of messages that do not seem to go away (each
morning I look at the oldest message, and the old message
does not go away).

I do have a job for cyr_expire in the /etc/cyrus.conf file.
