Hi, One of our scanner produces non-unique message-ids when sending mails. Ids are repeated in about a week. So I decided to have deliver.db purged at least once a day, because I have duplicatesuppression on in imapd.conf ####cyrus.conf EVENTS { checkpoint cmd="ctl_cyrusdb -c" period=30 delprune cmd="cyr_expire -E 1 -a -v" at=1015 tlsprune cmd="tls_prune" period=1440 } ########## deliver.db had 114 lines, I tried to set "at" to the time 5 min in the future. I waited for 10 mins. Log reported that cyr_expire ran, but deliver.db size and number of lines did not change. I have stopped cyrus, renamed deliver.db, started cyrus. And now deliver.db is quite small and not changing. -rw------- 1 cyrus mail 8,0K May 11 10:55 /var/imap/deliver.db What should I do anyway to fight that ugly scanner while keeping duplicatesuppression on ? __ Alexei Shilin cyrus-imapd 2.3.14-r3 Gentoo -- http://www.fastmail.fm - A no graphics, no pop-ups email service ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
