Hi, I'm using cyrus-imapd from the link below, rebuilt to use the log facility local6.* rather than rhel's choice of mail.*: http://www.invoca.ch/pub/packages/cyrus-imapd/cyrus-imapd-2.3.16-8.src.rpm I'm testing this is working with the following command on the master: /usr/lib/cyrus-imapd/sync_client -v -l -u user/info@xxxxxxxxxxxxx The log file seems happy enough: Sep 29 16:46:57 server17 sync_client[28162]: USER info@xxxxxxxxxxxxx Meanwhile on the mischievous slave: Sep 29 16:46:57 server18 syncserver[1413]: login: [my master] [my master's ip] cyrus PLAIN User logged in Sep 29 16:46:57 server18 syncserver[1413]: cannot unlink /var/lib/imap/domain/e/example.co.uk/user/u/user.info.seen: No such file or directory Sep 29 16:46:57 server18 syncserver[1413]: cannot unlink /var/lib/imap/domain/e/example.co.uk/user/u/user.info.mboxkey: No such file or directory Some non-default settings I have: On both master & slave: virtdomains: userid unixhierarchysep: yes hashimapspool: false On the master: sync_host: [my slave's hostname] sync_authname: cyrus sync_password: [my slave's cyrus password] sync_machineid: 2 sync_log: yes sync_repeat_interval: 5 I've configured their respective cyrus.conf's as laid out here: http://www.opensource.apple.com/source/CyrusIMAP/CyrusIMAP-187/cyrus_imap/doc/text/install-replication Not sure if this is still relevant but couldn't find the documentation against the version I'm using. Also not sure if this is relevant, but despite the fact I've got "sync_log: yes" in my master's imapd.conf, my /var/lib/imap/sync/ directory is empty. This is running on Linux server17.netring.co.uk 2.6.18-194.11.4.el5 #1 SMP x86_64 GNU/Linux, CentOS release 5.5 Any pointers in the right direction would be much appreciated!
