Are you running cyr_expire daily, like this? (it needs to
be in cyrus.conf)

EVENTS {
    checkpoint cmd="ctl_cyrusdb -c" period=30
    delprune cmd="cyr_expire -E 3" at=0400
    tlsprune cmd="tls_prune" at=0400
}

If you need to change your config to add cyr_expire, it is safe
to shutdown Cyrus and delete the deliver.db, then start it up
again.  We delete deliver.db on our systems every time we shut
down Cyrus.

No, sorry.  If you are running Cyrus 2.4.9 or later you can move
the deliver.db by setting the config variable duplicate_db_path.
Otherwise softlinks won't work, so you have no option with earlier
Cyrus versions.

Also, skiplist files are limited to 4Gb in size.  There is an
open bug for this.

I assume you speak Spanish?  Hopefully there are other Spanish
speakers on the list who can help you as well!
