Hello Cyrus users, I'm wonder about mails deduplication. I don't know hard link on linux, maybe you could help me to understand. I run 2.4.17-Invoca-RPM-2.4.17-6.el6 on Red Hat Enterprise Linux Server release 6.3 with singleinstancestore: 1. I send one mail to 1200 recipients in a single session (one queueid of Postfix). Then I go to fs and I list (ls -l) the email received by an account. I would read a value of 1200 on ls -l. Instead I read a very lower value, such as 161: -rw------- 161 cyrus mail 117838 Mar 27 15:19 2253. I'm a bit confused about Postfix lmtp_destination_concurrency_limit and lmtp_destination_recipient_limit. Now they are: lmtp_destination_concurrency_limit = 20 lmtp_destination_recipient_limit = 300 How can I set these limits to take benefit from mail deduplications? I also read this experience: http://docs.kolab.org/en-US/Kolab_Groupware/3.0/html/Administrator_Guide/chap-Administrator_Guide-Tweaking_Tips_for_Cyrus_IMAP.html#sect-Administrator_Guide-Tweaking_Tips_for_Cyrus_IMAP-Speeding_Up_Authentication Should I rise both limits to 1200? Thanks a lot Marco ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/ To Unsubscribe: https://lists.andrew.cmu.edu/mailman/listinfo/info-cyrus
