Expiry limit for the duplicate delivery database

[Gary Mills]

We are running cyrus-imapd-2.3.8 with this entry in /etc/cyrus.conf:

    delprune      cmd="cyr_expire -E 3" at=0400

I believe this is the default setting.  Is there any reason to keep
message IDs around for three days?  I'm wondering if reducing it to
one day will improve performance for local deliveries simply by making
the database smaller.  I assume that it would function equally well
in detecting mail loops with a one-day expiry.
