It can synchronize two imap mailbox, including SEENand ACL (but not quota or sieve script) You can sync all mailboxes at once using the cyrus manager account: 'cyrus' Here is a script I used for testing, I use ssh port fowarding to bypass IMAPS not very well supported by current imapsync # /bin/bash S_HOST=localhost T_HOST=fc8asx S_USER=cyrus T_USER=cyrus S_PASSWD=****** T_PASSWD=****** DOMAIN=mydomain.loc ssh -f -L 8143:127.0.0.1:143 $T_HOST sleep 60 /kolab/bin/perl -I/kolab/lib/emailgency/perl /usr/bin/imapsync \ --host1 $S_HOST --user1 $S_USER --authuser1 $S_USER --password1 $S_PASSWD \ --host2 127.0.0.1 --port2 8143 --user2 $T_USER --authuser2 $T_USER --password2 $T_PASSWD \ --include "^user/[EMAIL PROTECTED]" \ --syncacls \ /kolab/lib/emailgency/perl contains perl-Mail-IMAPClient-2.2.9 because imapsync like it Hope this help regards > > Any suggestions are greatly appreciated! > S.Waltz > ---- > Cyrus Home Page: http://cyrusimap.web.cmu.edu/ > Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki > List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html > -- Alain Spineux aspineux gmail com May the sources be with you ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
