I thought delprune at startup is standard and therefore I was wondering
that it takes so long and more evil the service is down while cleaning
up deliver.db. The debian/lenny cyrus.conf looks like this for the START
and EVENTS section. So disable delprune in the START section will solve
that problem? May be a good idea the post this to the debian Wishlist
for the cyrus package.

Ciap,
