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. -- -Gary Mills- -Unix Group- -Computer and Network Services- ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
