Afraid that replication in Cyrus doesn't support full master-master, only master/slave. UIDs in IMAP make full master-master rather involved. It is possible to run a mix of master and replica mailstores on a single system. > There are tools like nake_md5 and make_sha1, but the manpages document > only howto config them, but not how to realy use them for replication > check. I download the md5 files to a single location and run a 50 line Perl script to spot mismatches. You are welcome to a copy of that script. To make sure that the replica is up to date I run sync_client in an extra verbose mode (-v -v) and check for unexpected updates. Unfortunately that code didn't make it it into the vanilla Cyrus tree because of the reorganisation required to run sync_server from master using prot streams for communication. It wouldn't take a huge amount of effort to add "-v -v" into standard Cyrus. I believe that Fastmail have an external test suite which does spot checks on the master and replica versions of each account. This is the opposite approach, and makes sense if you have a convenient IMAP client library. -- David Carter Email: David.Carter@xxxxxxxxxxxxx University Computing Service, Phone: (01223) 334502 New Museums Site, Pembroke Street, Fax: (01223) 334679 Cambridge UK.
