Hi,

The question is why is the deliver db > 2GB in skiplist format? Is it
normal or do you have a corrupt BDB db or does your db pruning not work
for deliverdb. I think that should be something like 'delprune     
cmd="cyr_expire -D 7 -E 3 -X 7" at=0400' in cyrus.conf.

I think the easiest way would be to make sure you have pruning configured
correctly, then change config of deliver db to skiplist, and start without
a db so a new, empty deliver db is created.

Then have an eye on the db file to see if it grows again to almost 2GB. If
it doesn't grow so much, you should be fine.
