Hi all! I'm in the process of upgrading cyrus-imapd-2.2.13 (from Debian-3.1/Sarge) to cyrus-imapd-2.3.7 (from RHEL-5/CentOS-5) on a system with approx. 25k mailboxes. We are using quite simple sieve scripts for vacation and 2.3.7 duplicates (into the local inbox) all emails which trigger an outgoing vacation mail. Glancing over the source diff'ing the old and new imap/lmtp_sieve.c file (and diff'ing to 2.3.14) doesn't reveal anything remotely strange (to my eyes - I'm not experienced with cyrus-imapd's source code. So I may well looked into the wrong file.). Googling and searching in the bug/issue trackers from above also doesn't give any useful hint - and I didn't even found someone else having that problem. FWIW, we have "duplicatesuppression: false" in /etc/imapd.conf - as it saved a lot of I/O load on the old systems (avoiding storing and checking the for duplicates in the DB). Does anyone have any idea what could be wrong or what could/should be debugged/analyzed/....?
