Do you know imapsync ?
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 $T_PASSWD \
--include "^user/.*@${DOMAIN}" \
--syncacls \
/kolab/lib/emailgency/perl contains perl-Mail-IMAPClient-2.2.9
because imapsync like it
Hope this help regards
